Answer:
38 ft
Explanation:
Perimeter of the rectangle = 2* length + 2* width
Length of shaded part = Length of the larger rectangle - 4 = 11ft
width of the shaded part = width of the larger rectangle - 6 = 8 ft
Perimeter of the rectangle = 2* length + 2* width
Plug in the values of length and width
Perimeter of the shaded rectangle= 2(11) + 2(8)= 22+ 16= 38 feet
