Question

The length of a rectangle is

3
meters less than
3
times the width. The perimeter is
34
meters. Find the width.

Answer 1

Explanation:

Create a system of equation for this.

We know that the perimeter is 2L+2W so

2L+2W=34

And 3W+3=L

Replace L with 3w+3.

2(3w+3)+2w=34

Simplify.

6w+6+2w=34

8w+6=34

8w=28

w=3.5.

Width is 3.5 meters.
