Solution

Given, the length and breadth of a rectangular park are in the ratio 5:2.

Let the length and breadth of the rectangle be 5x,2x.
Then perimeter will be 2(5x+2x)=140.
According to the problem,
14x=140
or, x=10.
Then, length and breadth will be 50 cm and 20 cm.
Therefore, area will be =l×b=50×20=1000 cm2.
