a rectangular area is 5 m longer as it is wide.
\n" ); document.write( " one side of a square swimming pool will match exactly the width of the area .
\n" ); document.write( " after the pool is built the area left will be 30 m squared.
\n" ); document.write( " how wide is the area?
\n" ); document.write( ":
\n" ); document.write( "Let x = the width of the pool and the side of the square pool
\n" ); document.write( ":
\n" ); document.write( "Write an area equation
\n" ); document.write( "Rect area - pool area = 30 sq/m
\n" ); document.write( "x(x+5) - x^2 = 30
\n" ); document.write( "x^2 + 5x - x^2 = 30
\n" ); document.write( "x^2 - x^2 + 5x = 30
\n" ); document.write( "5x = 30
\n" ); document.write( "x = 30/5
\n" ); document.write( "x = 6 meters is the width
\n" ); document.write( ";
\n" ); document.write( ":
\n" ); document.write( "Check this, find the rect area and the pool area (rect length 6+5)
\n" ); document.write( "11 * 5 = 55 sq
\n" ); document.write( "5 * 5 = 25
\n" ); document.write( "--------------
\n" ); document.write( "left over 30 sq/ft \n" ); document.write( "
\n" );
