Carter plans to wallpaper the longest wall in his wall paper. the wall is twice as long as it is high and has a area of 162 feet. what is the height of the wall

9 ft

Step-by-step explanation:

The wall has the shape of a rectangle.  Let H represent the height of the wall.  Then, in terms of H, the length is 2H.  

The area of the wall is given:  162 ft.  This is equal to A = H(2H), or 2H^2.

Equating 162 ft and 2H^2, we get H^2 = 81, so that H must be 9 ft.

the answer is d on edge
