Question

A rectangle has width w and it's length is 2 units longer than the width, or w+2. Write a polynomial for the area of the rectangle.

Answer 1

Area = length x width



Width = w

length = w + 2



Area = w (w+2)

Area = w^2 + 2w

Answer 2

4w+4

Explanation:

The equation to find the length and width would be 2w+2 but since we need to find the perimeter we have to double it’s 2(2w+2) and the answer would equal to 4w+4

Please don’t trust the answer above me, it is incorrect. I wrote that as my answer and the teacher told me the correct answer is 4w+4. Don’t make the same mistake I did.
