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

Answer:

72 inches²

Step-by-step explanation:

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

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

$\frac{1}{2}l=w$

Plug in 12 inches as the length

$\frac{1}{2}(12)=w\\6=w$

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!
