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

Lemur [1.5K]

Answer:

The measure of the length is $23\ ft$

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

$P=2(x+y)$

$P=66\ ft$

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

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