You can put this solution on YOUR website!
If the length of the side of that square pool (in feet is $\"x\"$ .
\n" ); document.write( "the area of the pool (in square feet) is $\"x%5E2\"$
\n" ); document.write( " $\"x%5E2=196\"$
\n" ); document.write( "The positive solution is $\"x=14\"$
\n" ); document.write( "If you add 8 feet left and right, the total length of the deck (in feet) will be
\n" ); document.write( " $\"14%2B8%2B8=30\"$
\n" ); document.write( "The pool plus deck will be a square with a side length of 30 feet.
\n" ); document.write( "The perimeter (in feet) is
\n" ); document.write( " $\"4%2A30=120\"$
\n" ); document.write( "The outside perimeter of the deck is 120 feet. \n" ); document.write( "
