(25+2X)(10+2X)-25*10=74 THIS IS THE TOTAL AREA MINUS THE POOL AREA EQUALS 74 SQ FT.
\n" ); document.write( "250+20X+50X+4X^2-250=74
\n" ); document.write( "4X^2+70X-74=0
\n" ); document.write( "2(2X+35X-37)=0
\n" ); document.write( "(2X+37)(X-1)=0
\n" ); document.write( "X-1=0
\n" ); document.write( "X=1 ANSWER FOR THE WIDTH OF THE BORDER.
\n" ); document.write( "PROOF
\n" ); document.write( "(25+2)(10+2)-250=74
\n" ); document.write( "27*12-250=74
\n" ); document.write( "324-250=74
\n" ); document.write( "74=74
