Question
A rectangular plot has its length and breadth in the
ratio of 5:3. Aman riding a bicycle completes one round of this field along its perimeter at a speed of 6 kmph in 4 minutes. Then, What will be the area of the rectangular field?Solution
ATQ, we can say that Let the ratio be taken as 5a and 3a Let the perimeter of rectangular is = 2(l + b) Perimeter = 2(5a + 3a) = 16a Distance covered by the man = 6 x (5/18) x (4 x 60) = 400m Now, 16a = 400 a = 400/16 a = 25m Area of the rectangular field is = (5a x 3a) = 15 a2Â Â = 15 x 252 = 9375m2
