150 sq. ft.
Area of a triangle = (base x Height)/2 = 7 ft x 15 ft/2 = 105/2 sq ft= 52.5 sq ft
13' X 15' = 195 sq ft 195 sq ft / 9 = 21.67 sq yds
15 ft * 14 ft = 210 sq ft = 19.51 sq metres (to 4 sf).
240 square feet= 15 ft x 16 ft= 240 sq ft
150 sq. ft.
15 x 10 = 150 (sq ft).
15 ft * 15 ft = 15*15 sq ft = 225 sq ft
1 ft = 12 inches 1 sq ft = 12 x 12 = 144 sq in 10 sq ft = 10 x 144 = 1440 sq in
1 foot = 0.3048 metres soOption 1:15 feet = 15*0.3048 = 4.572 metres10 feet = 10*0.3048 = 3.048 metresSo 15 ft * 10 feet = 4.572 m * 3.048 m = 13.935 sq metres.Option 2:1 sq ft = 0.3048*0.3048 sq metres = 0.0929 sq metresSo 15 ft * 10 ft = 150 sq ft = 150 * 0.0929 = 13.935 sq metres.
