Question

A rectangle has a width that is 50% of its length. The length of the rectangle is 12 inches. What is the area of the rectangle. (Help!!)

Answer 1

72 inches²

Explanation:

Let
`w` be equal to the width of the rectangle.

Let
`l` be equal to the length of the rectangle.

`(1)/(2)l=w`

Plug in 12 inches as the length

`(1)/(2)(12)=w\\6=w`

Therefore, the width of the rectangle is 6 inches.

`A=lw`

Plug in 12 inches as the length and 6 inches as the width.

`A=(12)(6)\\A=72`

Therefore, the area of the rectangle is 72 inches².

I hope this helps!
