Question

The length of a rectangle is 4 times its width and the perimeter is 150
feet.
What is the width of the rectangle?
A. 15 feet

B. 75 feet

C. 30 feet

D. 60 feet

Answer 1

Answer:

Y = W = 15 ft.

X= L = 60 ft.

So width is 15 and the length is 60.

Answer 2

Answer: A. 15 feet

Step-by-step explanation:

The formula used to calculate the perimeter of a rectangle is:

$P=2l+2w$

Where "l" is the lenght of the rectangle and "w" is the width.

You know that the length of this rectangle is 4 times its width. This means that:

$l=4w$

And you know that the perimeter is 150 feet.

Then, you need to substitute  $l=4w$ and the value of the perimeter into the formula and solve for "w":

$150=2(4w)+2w\\\\150=10w\\\\w=\frac{150}{10}\\\\w=15feet$
