Question

Amber built a large rectangular garden that is 9 meters long and had an area of 72 square meters, what is the perimeter of amber's garden?

Answer 1

So we know that the length of the rectangle is 9 meters.

In order to find area of a rectangle, you multiply the length by the width.

To find the width, you divide the area by the side you do have , which is 9 meters.

72 divided by 9 is 8.

So the width 8 meters, and now to find the perimeter you must add all sides of the rectangle.

9+9+8+8 = 34.

The perimeter of the rectangular garden is 34 meters.
