Question

You are installing a window for a customer that has an area of 10 square feet. You know the length, or height, of the window is 5 feet. You need to determine the width of the window to cut the right size opening. Which formula can be used to find the width of the window?

A. width = length ÷ area
B. width = area ÷ length
C. width = area + length
D. width = 2(area + length)
E. width = area × length

Answer 1

To calculate the width of the window, you divide the area by the length which is option b , and for a window that is 10 square feet with a height of 5 feet, the width would be 2 feet.

Step-by-step explanation:

To find the width of a window when given the area and the length, you should use the formula for the area of a rectangle, which is length × width = area. Since we need to find the width and we have the area and the length, we need to isolate the width in this equation. Doing so, we divide both sides of the equation by the length, getting width = area ÷ length.

So for a window with an area of 10 square feet and a height of 5 feet, the formula to find the width would be B. width = area ÷ length. Therefore, the width would be 10 square feet ÷ 5 feet = 2 feet. This means the correct width for the window is 2 feet.
