8. A living room wall is 13 feet long. If the perimeter of the rectangluar living room is 56 feet long, what is the length of the other wall in the living room?

Step-by-step explanation:

A living room wall is 13 feet long. If the perimeter of the rectangular living room is 56 feet long.

The formula for the perimeter of the rectangular living room =

P = 2(L + W)

P = 2L + 2W

L = Length = 13 feet

W = Width

P = 56 feet

56 = 2 × 13 + 2 W

56 = 42 + 2W

56 - 42 = 2W

14 = 2W

W = 14/2

W = 7

The width of the rectangular room is 7 feet long

A rectangular room would have 4 walls
