Question

[15 POINTS] A rectangle has a width w and a length that is two more than its width. what is the perimeter of the rectangle? Write and simplify an expression.

Answer 1

Answer: P = 4w + 4

Step-by-step explanation:

width (w) = w

length (L) = w + 2  (2 more than its width)

Perimeter (P) = 2L + 2w

P = 2L + 2w

  = 2(w + 2) + 2(w)

  = 2w + 4   +  2w

  = 4w + 4
