Question 31
A rectangular plot is half as long again as it broad. The area of the lawn is 2/3 hectares. The length of the plot is?
Correct Answer: Option A
Let breadth = b meters.
then, length = 3b/2 meters
∴ b x 3b/2 = 2/3 X 10000
⇒ b2 = (4 x 10000)/9
⇒ b = ( 2 X 100)/3 m
∴ Length = (3/2) x (2/3) x 100 m
= 100 m
Question 32
The length of a plot is four times its breath. A playground measuring 1200 square meters occupies one third of the total area of a plot. What is the length of the plot in meters ?
Correct Answer: Option D
Area of the plot = (3 x 1200) m2
= 3600 m2
Let breadth = y meters
Then Length = 4y meters,
Now area = 4y x y = 3600 m2
⇒ y2 = 900 m2
⇒ y = 30 m
∴ Length of plot = 4y m
= (4 x 30) m
=120 m
