Answer:
40 square feet
Step-by-step explanation:
You want the area in square feet of a closet that is 10 feet long and 48 inches wide.
Area
The area is the product of the length and width. For area to be in square feet, both dimensions must be in feet.
12 in = 1 ft
48 in = 4 ft
Then the area is ...
A = LW = (10 ft)(4 ft) = 40 ft²
The area of the closet is 40 square feet.
