The perimeter of a rectangular playground is 40 yards. It is 11

2 yards

longer than it is wide. What is the area of the playground?

I can't figure out your text formatting, but

2(length + width) = 40
so figure out your numbers and plug 'em in.
Then as always,
area = length * width

If the perimeter of a rectangular playground is 40 yards it is one in a half yards lancer that it is wide what is the area of that playground
