Question

A rectangle has a length that is three times its width. Write an algebraic expression with four terms to represent the perimeter of the rectangle. Let w represent the width.

Answer 1

well, a rectangle has 4 sides, so that would be
w + 3w + w + 3w

Answer 2

The length of a rectangle is tree times the width. If the width is represented by ​, then write an algebraic expression that describes the length

Answer 3

Let x represent the length. 3x
