For area measurements, you multiply the length by the width. Here the calculation gives you an answer of 345 square feet.
if you want the square footage, 15 ft x 20 ft is 300 square feet
225 square ft.
135
Assuming the room is 15 ft by 10 ft (the question does not say so), the area would be 15*10 = 150 square feet.
165 feet squared
approx. 172.5 square feet
180 sq ft if 12 X 15 is actually 12 ft X 15 ft. Otherwise anything you like.
Square footage of the room = 14 ft * 8 ft = 14*8 sq ft = 112 sq ft.
To calculate square footage, you multiply the length by the width of the room. So, if the room measures 10 ft. by 18 ft., your total area is 180 sq. ft.
285 square feet. Just multiply length by width - the answer is the square footage.
160 ft. squared
72 sq. ft
