Answer:

Kindly check explanation

Step-by-step explanation:

Given the question :

Grace wove a potholder with an area of 80 square inches. The lengths and widths of the sides are whole numbers. Which dimensions make the most sense for a potholder?

Since the Area of the potholder = 80 sq inch

And the dimension of the potholder ; length and width are integers ; Hence, possible dimensions could be ;

Area = length × width

80 = length × width

(80, 1), (40, 2), (20, 4), (10, 8), (16, 5)

Potholders are fabrics sewn from the purpose of being used to handle pots and other kitchen equipments.

Usually the dimension are usually close, hence, the most sensible dimension a potholder with an area of 80 sq inch could have is 8 by 10 or vice-versa.

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
drek231 [11]
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.
