Hi,
*Note: the perimeter is all the way around the pen where one side is 18yd.
Let x be the length of the other side of the fence.
.
the question states the following to be true:
18 + 18 + x + x = 75
.
Combine like terms and solve:
2x = 39
x = 19.5 yds
.
Dimensions are 18yd by 19.5yd
.
Check Your answer:
18 + 18 + 19.5 + 19.5 = 75
