Question

a rectangle's length is three more than two times its width if the perimeter of a rectangle is 66 ft what is the measurement of the length​

Answer 1

The measure of the length is 23\ ft

Explanation:

Answer 2

The measure of the length is
`23\ ft`

Explanation:

Let

x-----> the length of rectangle

y-----> the width of rectangle

we know that

The perimeter of rectangle is equal to

`P=2(x+y)`

`P=66\ ft`

so

`66=2(x+y)`

Simplify

`33=x+y` -----> equation A

`x=2y+3` ----> equation B

Substitute equation B in equation A and solve for y

`33=(2y+3)+y`

`2y+y=33-3`

`3y=30`

`y=10\ ft`

Find the value of x

`x=2(10)+3=23\ ft`
