Question

the ratio between the length and the breadth of a rectangular Park is 3 ratio 2 is a man cycling along the boundary of the park at the speed of 12 km per hour completes one round in 8 minutes then find the area of the park ​

Answer 1

Perimeter = Distance travelled in 8 minutes,

=> Perimeter = 12000/60 * 8 = 1600 meter. [because Distance = Speed * Time]

As per question length is 3x and width is 2x

We know perimeter of rectangle is 2(L+B)

So, 2(3x+2x) = 1600

=> x = 160

So Length = 160*3 = 480 meter

and Width = 160*2 = 320 meter

Finally, Area = length * breadth

= 480 * 320 = 153600

Answer 2

Answer:153600
