195 square inches
(15 x 20) sq inches.
15 * 15 = 225 sq in
6 ft 10 in x 13 ft 10 in = 82 in x 142 in = 11,644 sq in = 11,644/144 sq ft = 80.86 sq ft I think that 13 ft 10 in = 166 inches, not 142 inches, so the answer is incorrect.
Assuming the height is 13 inches (not 13 feet or something else), Area = 0.5*(12+14)*13 = 169 sq inches.
About one hundred =========== 13 feet = 13 x 12 inches = 156 inches The area of a room 13 feet x 13 feet = 156 x 156 sq. in. = 24336 sq. in. area of 1 tile = 16 x 16 sq. in. = 256 sq. in. Dividing area of room (in sq. in.) by area of one tile: 24336/256 = 95.06 95 tiles are needed for a room 13' x 13'
11 in by 13 in encompasses 143 in2 (sq in)
Well, isn't that a happy little question! To find the square footage, you first convert the inches to feet by dividing by 12. So, 30 inches is 2.5 feet and 72 inches is 6 feet. Then you multiply the two dimensions together to get 15 square feet. Just imagine all the beautiful things you could create in that space!

That would be 169 square inches. Divide by 144 and you get 1.17 square feet.
144 sq inches in a sq. ft.
15 sq. feet
180 sq in. ... that's (12 X 15)/2 equals 180.
