Question

Consider the rectangle. Which pair of expressions represents the perimeter of the rectangle?

PLEASE HELP!!!

Answer 1

6x + 2 and 2x + (x + 1) + 2x + (x + 1)

Explanation:

Perimeter of a rectangle = 2(length + width)

Length = 2x

Width = x + 1

Perimeter of a rectangle = 2(length + width)

= 2{2x + (x + 1)}

= 2(2x + x + 1)

= 2(3x + 1)

= 6x + 2

Perimeter = length + width + length + width

= 2x + (x + 1) + 2x + (x + 1)
