Let the side of the square formed be x, then lenght = x+36, Breath = x-12
\n" ); document.write( "given the area of rectangle = area of the square.
\n" ); document.write( "(x+36)(x-12) = X^2
\n" ); document.write( "X^2 +36x-12X+432 = x^2
\n" ); document.write( "24x+432=0
\n" ); document.write( "24x = 432
\n" ); document.write( "x = 18\r
\n" ); document.write( "\n" ); document.write( "Length = 18+36 = 54
\n" ); document.write( "Breath = 18 - 12 = 6\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
\n" );
