Respuesta :

l  = 14 - 6 = 8
w = 15 - 4 = 11

P of shaded = 2(8+9) = 2 (19) = 38

answer
last one 38ft

Answer:

38 ft

Step-by-step 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
