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

A. 15 feet

Step-by-step explanation:

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

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:

And you know that the perimeter is 150 feet.

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

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
