For area measurements, you multiply the length by the width. Here the calculation gives you an answer of 160 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.

11 square meters is 118.403 square feet.
It is: 14*11 = 154 square feet
10 x 11 = 110 square feet.
25' x 11' = 275 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
