A. At its midpoint on the opposite side
5 times 4 equals 20
2 times 10 equals 20
To find the area<span> of a rectangle, multiply the length by the width</span>
- Square Area:
, with s = length of side
Plug in the side length into the square area and solve for the area as such:

<u>The area of the pool is 9a^10 un^2.</u>
{[12 ÷ 4] + [16 ÷ 8 (7 – 5)]} – 1.
{[3] + [2(2)]} – 1.
{[3] + [4]} – 1.
7-1
