Question

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

Explanation:

Step1: Recall the area formula for a square

The area \( A \) of a square is given by the formula \( A = s^2 \), where \( s \) is the side length (which is also the height, since it's a square).

Step2: Substitute the given area into the formula

We know the area \( A = 100 \) square feet. So we set up the equation \( 100 = s^2 \).

Step3: Solve for \( s \)

To find \( s \), we take the square root of both sides. \( s=\sqrt{100} \). Since the square root of 100 is 10 (because \( 10\times10 = 100 \)), we get \( s = 10 \).

Answer:

The height of the mural is 10 feet.
