Question

The length of a rectangle is three less than twice the width. If the perimeter of the rectangle is 84​ meters, what are the length and​ width?

Answer 1

l= 27

w= 15

Explanation:

Let the width be represented by w.

Based on the information given, the length will be:

= (2 × w) - 3

= 2w - 3

Therefore, the perimeter will be:

2(w) + 2(2w - 3) = 84

2w + 4w - 6 = 84

6w = 84 + 6

6w = 90

w = 90/6

w = 15

Therefore, the length will be:

L = 2w - 3

L = 2(15) - 3

L = 30 - 3

L = 27 feet

The length is 27 feet
