Marks: +1, -0

The ratio between the length and breadth of a rectangular park is 3 : 2. If a man cycling along the boundary of the park at the speed of 12 km/h completes one round in 8 min, then the area of the park in sq m is

15360
153600
30720
307200

Solution:

(b) Let length and breadth of the rectangular park be 3x and 2x, respectively.
Then, using the formula, distance = speed x time
10x = 1 2 x

5/18

x 8 x 60
⇒ x =160
∴ Area of rectangular park = 3x × 2x
= 6

x^2

= 6 x

(160)^2

= 6 x 25600
= 153600 sq m
