Algebra.Com's Answer #155396 by Targetweek(62)![]() ![]() ![]() 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( " \n" ); document.write( "Simplify down to a \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! \n" ); document.write( " |
