Suppose the width of the path is x. the dimensions of the extended rectangle are (12+x+x), and (16+x+x) (12+2x)(16+2x)=285 4x²+56x+192=285 4x²+56x-93=0 Not easy to factor it, so use the quadratic formula to solve: x={-56+√[(56²-4*4*(-93)]}/2*4 or x={-56-√[(56²-4*4*(-93)]}/2*4 x=1.5 (ignore the negative solution.)
I used a converter so i put 3200 meters into feet which was 10,498.69 and i rounded it to 10,498 and then i subtract 10,498 feet from 11,808 feet and got 1,310 feet as the answer
