NCERT Textbook Page 116
Mark the Route
1) Trace the route of the parade in Map 3 and mark India Gate and Rajpath.
Answer.
The route of the parade has been traced below with pink colour. The Rajpath and India Gate have been marked on the map as shown below:
2) Look at the map carefully and find out:
(a) Which of these is the longest road?
• B.S. Zafar Marg • Subhash Marg • Tilak Marg
(b) If Rubia is coming from Jama Masjid to join the parade, guess about how far she will have to walk.
(c) The total route of the parade is about how long?
• 3 km • 16 km • 25 km • 8 km
Answer.
(a) Subhash Marg is the longest road.
(b) Jama Masjid is 1 cm away from the Subhash Marg which is the route of the parade.
Now Scale is: 2 cm = 1 km = 1000m
So 1 cm = 1000/2 = 500m
Thus, Rubia will have to walk about 500 m to join the parade.
(c) Total distance of the route of parade in the map is 16 cm.
We know that, 2 cm on map = 1 km
Or 1 am = 0.5 km
∴ 16 cm = 16 × 0.5 = 8 km
So, Total distance of the route of parade = 8 km.

(a) Which of these is nearer to river Yamuna? — the Diwan-e-Aam or the Diwan-e-Khaas?
(b) Between which two buildings is Aaram Gah?
(c) Which buildings do you pass while going from Rang Mahal to the Hammam?
(d) Which building on this map is farthest from Meena Bazar?

(b) Aaram Gah is between Diwan-e-Khas and Rang Mahal.
(c) While going from Rang Mahal to Hammam we pass through Aram Gah and Diwan-e-Khas.
(d) Hammam is farthest from Meena Bazar.
(e) Distance of Lahori Gate from Diwan-e-Khas is about 6 cm on map.
Now Scale: 1 cm = 100 m
So, total distance of Lahori Gate from Diwan-e-Khas = 6 ×100 = 600 m

1. Here are some pictures drawn on a 1 cm square grid. Try making the same pictures on a 2 cm grid and also on a 1/2 cm grid. One picture is already done. The side of the square was made two times bigger. Does its area also become two times bigger?
Answer.
The area of square = side x side = side2
When sides are doubled then
New area of square = 2 x Side x 2 x Side = 4 x side2
So, when the side of the square is made 2 times bigger, then its area becomes 4 times bigger than the original area.

Now Try This
This is a part of the parade-route Map 3.
1) Can you see which part of the rout-map it is?
2) Now try to make it bigger in this 2 cm grid. Remember that the ‘shape’ of the map should not change.
3) If the parade route map is smaller, and the distance between India Gate and Vijay Chowk becomes 2 cm, what would be its scale?
- 1 cm on map = 1 km on ground
- 12cm on map = 1 km on ground
- 2 cm on map = 1 km on ground
Answer.
1) Given part of the parade map is marked below:
2) Given part of map can be drawn on a 2 cm grid as shown below:
3) The distance between Vijay chowk and India gate on the map = 4 cm
Here Scale is as 2 cm = 1 km
If the distance between Vijay chowk and India gate becomes 2 cm, then the scale will be
1 cm on map = 1 km on ground

(A) About how far is Delhi from Jaipur?
(a) 50 km (b) 500 km (c) 250 km
(B) Estimate, how far is Jaipur from Bhopal?
On the map = _______ cm.
On the ground = _______ km.
Answer.
(A) (c) 250 km
Distance between Delhi and Jaipur on map is about 1.2 cm.
Here scale is: 1 cm = 200 km
So distance between Delhi and Jaipur on ground = 1.2 × 200 km = 240 km
(B) On map the distance between Bhopal and Jaipur is about 2.4 cm.
And Scale is 1 cm = 200 km
So, the distance between Bhopal and Jaipur on ground = 2.4 × 200 km = 480 km
Thus, On the map = 2.4 cm.
On the ground = 480 km.

Distances between Towns
These are five towns. Find out:
1) How many cm away is Idlipur from barfinagar on the map?
2) How many kilometres will you have to travel if you go from Idlipur to Barfinagar?
3) There is a place called Thukpagram midway between Idlipur and Barfinagar. Mark it with a ‘T’.
4) A town called Jalebipur is 35 kms away from both Chholaghat and Dhoklabad. Where do you think it can be? Mark ‘J’ for it.
5) Measure the length of the route between Bhelpur and Chholaghat. (You can use a thread)
Answer.
1) Idlipur is about 5 am away from Barfinagar on the map.
2) Distance between Idlipur and Barfinagar on the map = 5 cm
Now, scale is 1 cm = 10 km
Thus, Distance between Idlipur and Barfinagar on ground = 5 × 10 = 50 km
Thus, we have to travel 50 km if we go from Idlipur to Barfinagar.
3) The place Thukpagram which is located midway between Idlipur and Barfinagar is marked with T as shown below:
4) Jalebipur is 35 km away from both Chholaghat and Dhoklabad.
Here the scale is 1 cm = 10 km
Or 10 km = 1 cm
Or 1 km = 1/10 = 0.1 cm
Thus, Distance of jalebipur from both Chholaghat and Dhoklabad on map = 0.1 × 35 = 3.5 cm
So we can mark Jalebipur at a distance of 3.5 cm from both Chholaghat and Dhoklabad as shown below:
5) Distance between Bhelpur and Chholaghat on map is about 6 cm.
Here, the scale is 1 cm = 10 km
So, distance between Bhelpur and Chholaghat on ground = 6 × 10 = 60 km

Ashi’s School
Ashi’s school looks like this from the top.
Use the squares to find out:
1) How many times bigger is the area of the Assembly ground than that of the office?
Answer.
The assembly ground covers 15 complete squares and office covers 3 complete squares.
Thus, the area of the Assembly ground is 5 times that of the office.
2) How much is the length and width of each classroom?
(a) length 5 m, width 4 m
(b) length 2 m, width 1 m
(c) length 12 m, width 10 m
(d) length 5 m, width 5 m
Answer.
(a) length 5 m, width 4 m
Here, the scale is 2 cm = 5 m
Or 1cm = 5/2 = 2.5 m
Length of a classroom on map = 2 cm
Thus, length of classroom on ground = 5 m
Breadth of a classroom on map = 1.6 cm
Thus, breadth of classroom on ground = 1.6 × 2.5 = 4 m
3) All the classrooms in Ashi’s school look like this.
Look carefully and answer.
(a) Which of these is exactly opposite to the blackboard?
Almirah, windows, notice board, display board
