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​

Respuesta :

Answer:

The measure of the length is [tex]23\ ft[/tex]

Step-by-step explanation:

Let

x-----> the length of rectangle

y-----> the width of rectangle

we know that

The perimeter of rectangle is equal to

[tex]P=2(x+y)[/tex]

[tex]P=66\ ft[/tex]

so

[tex]66=2(x+y)[/tex]

Simplify

[tex]33=x+y[/tex] -----> equation A

[tex]x=2y+3[/tex] ----> equation B

Substitute equation B in equation A and solve for y

[tex]33=(2y+3)+y[/tex]

[tex]2y+y=33-3[/tex]

[tex]3y=30[/tex]

[tex]y=10\ ft[/tex]

Find the value of x

[tex]x=2(10)+3=23\ ft[/tex]

Answer:

The measure of the length is 23\ ft
