Answer:
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
