# Peter and Ray built a bike ramp from 20 sheets of 4ft. X 8ft.

Peter and Ray built a bike ramp from 20 sheets of 4ft. X 8ft. plywood and propped it up on one end with some bricks. The finished ramp is rectangular. Show 3 ways they might have arranged the wood and give the measurment for each side. Assuming that they used every sheet of plywood, what is the total area of the ramp regardless of its shape?

20 = 1*20 = 2*10 = 4*5

So, the three ways are 1 sheet by 20 sheets, 2 sheets by 10 sheets, and 4 sheets by 5 sheets.
