The ratio between the length and the breadth of a rectangular park is 3: 2.
Question 1:
The ratio between the length and the breadth of a rectangular park is 3: 2. If a man cycling along the boundary of the park at the speed of 12 km/hr completes one round in 8 minutes, then the area of the park (in sq. m) is:
A.15360
B.153600
FeedbackPerimeter = Distance covered in 8 min. =12000x 8m = 1600 m. Let length = 3x metres and breadth = 2x metres. Then, 2(3x + 2x) = 1600 or x = 160. Length = 480 m and Breadth = 320 m. Area = (480 x 320) m2 = 153600 m2.
C.30720
D.307200
