Question

The length of a rectangle is twice the width. The area is 392 yd². Find the length and width.​

Answer 1

L=28 yd

W=14 yd

Explanation:

Here's what we know:

Length=L

Width=W

L*W=392 yards^2

L=2*W

We rewrite the equation to look like:

2W*W=392 yd^2

So, the simplified version of the new equation is 2W^2=392 yd^2

To find the answer, divide both sides by 2, and you'll find that W^2=196. To find W, simply take the square root of both sides and you'll find that W=14 yd

Now that you know what W is, you can plug it back into the equation for length.

L=2(14)

L=28 yd
