Use the image to answer the question. Tessa designs a supply closet as an addition to her house. The closet is pictured, and its total area is 36 square feet. What is the length in feet of the side of the supply closet labeled with the question mark?(1 point) feet
The area of a rectangle is calculated by multiplying the length and width. In this case, we have the total area of the supply closet as 36 square feet.
Let's denote the length of the side labeled with the question mark as "x". Since the closet is a rectangle, the width of the closet will be the total area divided by the length.
Therefore, x * x = 36
x^2 = 36
To find the value of x, we need to take the square root of both sides because the area of a rectangle is a squared number.
√(x^2) = √36
x = 6
Therefore, the length in feet of the side of the supply closet labeled with the question mark is 6 feet.
