PLEASE HURRY, 20 POINTS A rectangle’s area and perimeter have the same numerical value. The length of the rectangle is 12 feet. What is the width of the rectangle in feet? Enter your answer as a decimal in the box.

Step-by-step explanation:

A rectangle's perimeter is given by the formula:

A rectangle's area is given by the formula:

We are given that they have the same numerical value. In other words:

And we are also given that the length is 12 feet. So, substitute 12 for l:

To solve for the width, we just need to solve for w.

On the left, distribute:

Subtract 2w from both sides. The left side cancels:

Divide both sides by 10. Flip also:

Reduce both layers. Use 2. So:

So, the width is 2.4 feet.

And we're done!
