Question

The length of a rectangle is
2
meters less than
3
times the width. The perimeter is
36
meters. Find the width.

Answer 1

Answer:

5

Step-by-step explanation:

Let x = the width

3x-2 is the length

To find the perimeter is it is 2l plus 2w

2(3x-2) plus 2(x)

6x-4+2x

8x-4

36=8x-4

add to both sides

40=8x

divide both sides by 8

x=5
