Answer:
If you are using graph paper, you would go across 10 squares and up 8 square. Since two of each side are equal, both the lengths would be 10 on each side along with the 8 for the width. You would end up with a total of 80 square units, and in this case the units are labeled as feet so you would have 80ft^2. If you are going to figure this out by using the formula, you just take the length (10) multiplied by the width (8) for the same answer of 80ft^2.
