figure to the nearest whole unit.
"A mural with an Area of 81 units2"
(Hint: what is the side length of the square.)
HELP PLEASE

Answer 1

Answer:
`9\ units`

Explanation:

You need to use the following formula for calculate the area of a square:

`A=s^2`

Where "s" is the lenght of any side of the square.

You know that the area of a mural is
`81\ units^2`. 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=√((81\ units^2))\\\\s=9\ units`
