25 square feet.
If you mean 75 feet x 15 feet then the square footage is 1,125 square feet.
15 feet x 15 feet = 225 square feet.
The question does not give the units of measurement for the room's size. Assuming they are feet, the square footage is 12*15 = 180 square feet.
240 square feet. (16 x 15 = 240)
225 square feet (15 x 15 = 225).
Oh, dude, you're hitting me with some math here! So, to find the square footage of a rectangle, you just multiply the length by the width. In this case, 36 inches by 60 inches equals 2,160 square inches. To convert that to square feet, you divide by 144 (since there are 144 square inches in a square foot), giving you 15 square feet. Easy peasy, right?
If you mean 75 feet x 15 feet then the square footage is 1,125 square feet.
15 * 20 = 300 square feet.
Simply put multiply 15 by 40 to get the square footage. This would be 600 square feet.
15 feet x 15 feet = 225 square feet.
