Richard is building a rectangular playground from 200 feet of fencing. The fencing must entirely enclose the playground. What is the maximum area of this playground?
I don't understand
Ok, thanks.
It can be shown that the max area is when each side of the rectangle = 200/4 = 50ft
So...the rectangle is a square
So.....the max area is 50^2 = 2500 ft^2
+80
