Step-by-step explanation:

A. The base of the triangle is 8 feet and its height is 2 feet. The square has an area of 64 square feet and the triangle has an area of

8 feet×2 feet2=8 square feet.

So the total area of the wall is 64 + 8 = 72 square feet.

b. Jamie will need to cut the strips since the top of the wall does not lay horizontally while the top of the vertical strips of wallpaper will lay horizontally. One nice way Jamie could cover the wall with vertical strips would be to make cut two 18 foot strips of paper. Each of these strips then needs to be cut ''diagonally,'' eight feet up one side and nine feet up the other side

C. With horizontal strips of wallpaper, 4 strips, each 8 feet long, will cover the square part of the wall leaving the triangle at the top. Jamie can next take a 4 foot long strip of wallpaper, making a 2 foot by 4 foot rectangle. If this rectangle is cut diagonally, Jamie gets two right triangles measuring 2 feet by 4 feet and these can be placed at the top of the wall
