# Geometry

Hi, I have a quick question that needs to be answered:
If plywood came in pieces that measure 8feet by 4feet, how many pieces of plywood are need to cover the roof (which has a base of 42 feet and a height of 25 feet)?
I would also like to ask you is it possible that you explain in detail how you retrieved your answer so I can get why the answer to the problem resulted as so.
Thank you,
Beautiful

Scale the graph paper: let each unit be 1 ft.

Cut off some of the rectangles representing the plywood. Work this as you would a jigsaw puzzle.
