Ramesh rides along the boundary of a rectangular park at the rate of 12 km/hr and completes one full round in 15 minutes. If the length of the park is 4 times its breadth, then what is the area of the park?
let width=x and length=4x
perimeter of rectangular field=2(l+b)
ramesh rides 3km of distance.
length=1.2km and width=0.3km
area of rectangular field=0.3 * 1.2 = 0.36 square km
