Question

Suppose the length of a rectangle is 3 units greater than its width. If the width is w, what expression gives the perimeter of the rectangle in terms of its width?

Answer 1

P = 6 + 4w

Explanation:

The length of a rectangle is 3 times greater than its width

Therefore the perimeter of a rectangle can be calculated as follows

P= 2L + 2w

P = 2(w + 3) + 2w

P= 2w + 6 + 2w

P= 6 + 4w

Hence the expression which gives the perimeter of the rectangle in terms of its width is P = 6 + 4w
