For area measurements, you multiply the length by the width. Here the calculation gives you an answer of 160 square feet.
11 in by 13 in encompasses 143 in2 (sq in)
121 square feet.
11 square meters is 118.403 square feet.
x = the width of the path. A = area of path = (15+x)(11+x) - (15*11) = (15*11)+15x+11x-(15*11) = 15x+11x = 26x 192 ft2 = 26x x = 192/26 ~= 7.38 feet.
10 x 11 = 110 square feet.
25' x 11' = 275 square feet
It is: 14*11 = 154 square feet
11" by 50' is 45.83 square feet.
14 * 11 = 154 square feet!
There are: 11 feet times 7 feet = 77 square feet
121
121 square feet. To calculate square feet simply multiply length by width - the result is the area in square feet.
