Answer:

D) 24x + 52

Step-by-step explanation:

The perimeter of the purple rectangle is

P =2(l+w)

=2 (4x+5 + 2x+7)

Combine like terms

=2 (6x+12)

Distribute

= 12x +24

The perimeter of the white rectangle is

P =2(l+w)

P =2(3x+14 +3x)

Combine like terms

=2(6x+14)

Distribute

12x +28

Add the perimeters

12x +24 + 12x +28

24x +52
