Let $\"s\"$ = a side of the square fountain
\n" ); document.write( "The walk adds $\"2%2A3.5+=+7\"$ ft to the width
\n" ); document.write( "given:
\n" ); document.write( " $\"+%28s+%2B+7%29%5E2+=++700+\"$
\n" ); document.write( "Take the square root of both sides
\n" ); document.write( " $\"+s+%2B+7+=+10%2Asqrt%287%29+\"$
\n" ); document.write( " $\"+s+=+26.457+-+7+\"$
\n" ); document.write( " $\"+s+=+19.457+\"$
\n" ); document.write( "The fountain measures 19.457 x 19.457 ft2 \n" ); document.write( "
