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?
1 foot is 12 inches, therefore 1 square foot is (12 x 12) = 144 square inches. To determine the number of square feet, divide the number of square inches by 144 (the number of square inches in a square foot). 1800 / 144 = 12.5 square feet.
1,385 square inches = 9.62 square feet
