Answer:

Outside rectangle = 88 inches

Inside rectangle = 44 inches

Step-by-step explanation:

Length of the outside rectangle = 24¾ inches = 24.75

Width of the outside rectangle = 5½ inches + 8¼ inches + 5½ inches = 5.5 + 8.25 + 5.5 = 19.25 inches

Perimeter of rectangle = 2(L) + 2(W)

Perimeter of outside rectangle = 2(24.75) + 2(19.25) = 49.5 + 38.5 = 88 inches

Length of inside rectangle = 24¾ - (5½ + 5½) = 24.75 - 11 = 13.75 inches

Width of inside rectangle = 8¼ = 8.25 inches

Perimeter of insides rectangle = 2(13.75) + 2(8.25) = 27.5 + 16.5 = 44 inches
