Answer:
Explanation:
Let w = the width.
So then the length is w + 3.
The formula for the perimeter of a rectangle is 2 (L+W), or in this case, 2 (w + 3 + w) = 2 (2w + 3) = 4w + 6.
We know that's equal to 30, so let's solve for w:
4w + 6 = 30
4w = 24
w = 6
Since the length is 3 more than the width, the length must be 9.
Therefore the area is 6 * 9 = 54 square yards.
