Question 831290
First, understand what a perimeter is.  It is the total distance around the borders of the court.  That said, begin by translating to algebraic expressions.  This will be a system of two equations:

L = 2W + 2
2L + 2W = 238

First, begin by substituting 2w+2 for L:

2(2w+2) + 2w = 238
4w + 4 + 2w = 238
6w + 4 = 238
6w = 234
w = 39
L = 2(39) + 2
L = 78 + 2
L = 80

So your court dimensions are 80' by 39'.
