Question

What is the combined perimeter of these two rectangles?

Answer 1

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

Answer 2

Answer:

The Answer is D) 24x + 52

Step-by-step explanation:

Find the perimeter of each rectangle and then add them together. The perimeter of the first rectangle is 12x + 24 and the perimeter of the second rectangle is 12x + 28. The combined perimeter is 24x + 52
