Explanation / Answer
Let the length be l and width be w.
Given l = 4 + 2w feet
=> l - 2w = 4 (1)
Perimeter :
2l+2w = 248 (2)
Adding (1) and (2)
=> 3l = 252
=> l = 252/3 = 84 feet
Substituting in (1)
=> 84 - 2w = 4
=> 2w = 80
=> w = 80/2 = 40 feet
The length of the court is 84 feet
The breadth of the court is 40 feet.
