Question

The width of a rectangle is 9 cm less than twice the length. the perimeter is 72 cm. What is the length and width

Answer 1

9 times 9=72

Step-by-step explanation:

if if the width is 9 then the length is 9 because 9 times 9 equals 72

Answer 2

Answer:

The length is 15

The width is 21

Step-by-step explanation:

Say the length of the rectangle is x.

Then, the width would be 2x-9.

You can use this to make the equation

x+x+2x-9+2x-9=72

6x-18=72

6x=90

x=15

2x-9=30-9=21

Therefore,

The length is 15

The width is 21
