Answer: ![9\ units](https://tex.z-dn.net/?f=9%5C%20units)
Step-by-step explanation:
You need to use the following formula for calculate the area of a square:
![A=s^2](https://tex.z-dn.net/?f=A%3Ds%5E2)
Where "s" is the lenght of any side of the square.
You know that the area of a mural is
. Then, you can substitute this area into the formula and solve for "s", in order to find the side lenght of the mural.
Therefore, this is:
![81\ units^2=s^2\\\\s=\sqrt{(81\ units^2)}\\\\s=9\ units](https://tex.z-dn.net/?f=81%5C%20units%5E2%3Ds%5E2%5C%5C%5C%5Cs%3D%5Csqrt%7B%2881%5C%20units%5E2%29%7D%5C%5C%5C%5Cs%3D9%5C%20units)
After Doing the math the answer is 72 Inches or 6 feet
