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?

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

Explanation

For a rectangular window, area = length × width. Rearranging gives width = area ÷ length, so the width is 10 ÷ 5 = 2 feet. The correct choice is “width = area ÷ length.”
