Question

An artist frames his rectangular artwork. The length of his art is 3 times the width, w. How can he represent the perimeter of the art? Match each reason on the left to the expression it describes.

Answer 1

Perimeter = 8w

Explanation:

Let the width of the rectangular framework be w.

Length = 3w

We know that the perimeter of a rectangular shaped object is given by :

P = 2(l+w)

Substitute all the values in the above formula,

Perimeter = 2(3w+w)

= 2(4w)

= 8w

So, the perimeter of the art be 8w.
