The length of one side of the pool if the pool has an area of 121 square feet is 11 feet
The formula for calculating the area of the square pool is expressed as:
[tex]A_s=L^2[/tex]
L is the length of one side of the pool
If the area of the square pool is 121 square feet, hence;
[tex]121 = L^2[/tex]
Take the square root of both sides;
[tex]\sqrt{121}= \sqrt{L^2}\\ \sqrt{121}=L\\11=L\\Swap \ sides\\L = 12ft[/tex]
Hence the length of one side of the pool if the pool has an area of 121 square feet is 11 feet.
