Shorter side = x \n" ); document.write( "Longer side = 3 + x \n" ); document.write( "Perimeter = 2*shorter side + 2*longer side \n" ); document.write( "54 = 2(x) + 2(3 + x) \n" ); document.write( "54 = 2x + 6 + 2x \n" ); document.write( "54 - 6 = 4x \n" ); document.write( "48 = 4x \n" ); document.write( " x = 12 \n" ); document.write( "Shorter side = 12m \n" ); document.write( "Longer side = 15m \n" ); document.write( "Area of rectangle = 12 * 15 \n" ); document.write( "Area of rectangle = 180m^2 \n" ); document.write( "Hope this helps. \n" ); document.write( ":-) \n" ); document.write( " |
