Question

what is the height of the mural? selenas class is painting a mural on the wall of her school. the mural is a square with an area of 100 square feet.

Explanation:

Step1: Recall area formula for square

For a square, the area formula is $A = s^2$, where $A$ is the area and $s$ is the side - length (which is also the height in case of a square).

Step2: Solve for side - length

Given $A = 100$ square feet. We have $s^2=100$. Taking the square root of both sides, $s=\sqrt{100}$.

Step3: Calculate the value

$\sqrt{100}=10$ feet.

Answer:

10 feet
