a) 124
b) 144
c) 165

24. Radha wishes to start a 100sq m rectangular vegetable garden. Since he has only 30m wire, he fences three sides of the garden letting his house compound wall act as the fourth side fencing. The dimension of the garden is.
a) 15m * 6.67m
b) 20m * 5m
c) 30m * 3.33m
d) 40m * 2.5m
e) None of these
Answer (b) Explanation:
According to question, 2b + L = 30, (as fencing is only for 3 sides)
So, L = 60 – 2b
Now area of the garden = 200 sq m,
L * b =200, OR b*(60 - 2b) = 200
b2 - 15b + 50 = 0,
Now b = 5 & b=10
if b = 5 then L = 20 and if b= 10 then L= 10
Since the garden is rectangular so the dimension would be 20m * 5 m
