Notice that one side of the playground does not require fencing.
1250 ft2
Let's define a variable for each dimension of the rectangle. Let w be the width and ℓ be the length.
The perimeter of a rectangle is P=2ℓ+2w, but one side does not require fencing. This means the perimeter of the playground is P=2ℓ+w. Since there is 100 ft of fence, then 2ℓ+w=100, which means that w=100−2ℓ.
