Question

The dimensions of a rectangle are shown. What is the perimeter, in units of the rectangle?

Answer 1

Answer: 16x+20

Explanation:

perimeter of a rectangle is the length of all sides added together.

(3x+8)+(3x+8)+(5x+2) + (5x+2)

combine like terms

16x+20

Answer 2

the perimeter, in units of the rectangle is 16x + 20

Explanation:

perimeter of a rectangle be is 2(L + B)

p = 2(L + B)

L = 5x + 2

B = 3x + 8

p = 2L + 2B

p = 2(5x + 2) + 2(3x + 8)

p = (10x + 4) + (6x + 16)

p = 10x + 4 + 6x + 16

Collect like terms

p = 10x + 6x + 4 + 16

p = 16x + 20
