Question

The length of a rectangular park is 18m more than its breadth if it's perimeter is 84m find the dimensions of the park

Answer 1

consider the breadth to be X then length of the park will be 18+X
now perimeter =2(l+b)
so
84=2(18+X+X)
42=18+2x
24=2x
x=12
thus breadth is 12 and length is 30
