You can put this solution on YOUR website!
First find the area of the rectangle to be enclosed
\n" ); document.write( "then increase the dimensions of the rectangle by 1 foot on all sides (in other words increase it to 92x122)
\n" ); document.write( "Next find the area of the new larger rectangle and then subract the area of the original rectangle from it
\n" ); document.write( "That's how many square feet a 1ft wide sidewalk will require
\n" ); document.write( " But to find exactly how wide to make it i would set it up algebraicly
\n" ); document.write( "like so...
\n" ); document.write( "\"%28x%2B90%29%28x%2B120%29+-+10800+=+1744\"
\n" ); document.write( "Simplify down to a \"ax%5E2%2Bbx%2Bc+=+0\" form
\n" ); document.write( "Then Graph and and find solutions (the x-intercepts) or try to factor and solve that way or even the quadratic formula\r
\n" ); document.write( "\n" ); document.write( "hope that helped!
