15 feet x 15 feet = 225 square feet.
if you want the square footage, 15 ft x 20 ft is 300 square feet

165 square feet
Multiply the two dimensions: 25*15 = 375 sq ft
3*5 = 15 square feet.

Simply put multiply 15 by 40 to get the square footage. This would be 600 square feet.
Multiply the two dimensions: 25*15 = 375 sq ft
That's 225 Sq. Ft. (15X15)
285 square feet. Just multiply length by width - the answer is the square footage.
3*5 = 15 square feet.
Assuming the room is 15 ft by 10 ft (the question does not say so), the area would be 15*10 = 150 square feet.
