Question 629611
you could make the path 4 feet wide....

your dimensions are 18' x 15'  i guessed it right the first time by trying a 4 foot wide path, sooooo...
lets find out exactly how long it will be
your short side, 15', thats gonna be two sides, so 15 x 2 is 30
your long side is 18 feet, we're estimating a 4 foot wide path, so we're gonna need to add 4 feet to each side of the 18' so that it overlaps the 15' sides, so that makes 2 sides of 26' long, both added up make 52'
add 52 to 30 and you get 82
multiply 82' by 4' and you will get 328 square feet
