195 square inches
30 inches x 72 inches = 2.5 ft * 6 ft = 15 sq ft.30 inches x 72 inches = 2.5 ft * 6 ft = 15 sq ft.30 inches x 72 inches = 2.5 ft * 6 ft = 15 sq ft.30 inches x 72 inches = 2.5 ft * 6 ft = 15 sq ft.
(15 x 20) sq inches.
530.9 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)
That would be 169 square inches. Divide by 144 and you get 1.17 square feet.

13' X 15' = 195 sq ft 195 sq ft / 9 = 21.67 sq yds
