Perimeter of a rectangle = 2 * length + \n" ); document.write( "2 * width. \n" ); document.write( "64 = 2x + 30 \n" ); document.write( "2x = 64 - 30 \n" ); document.write( "2x = 34 \n" ); document.write( "x = 17 \n" ); document.write( "Length = 17cms \n" ); document.write( "Therefore Area = length * width \n" ); document.write( " = 17cms * 15cms \n" ); document.write( " = 255 cm^2 \n" ); document.write( "If the rectangle is divided into 2 \n" ); document.write( "Each triangle would have an area \n" ); document.write( "of 255/2 = 127.5 cm^2 \n" ); document.write( "Hope this helps. \n" ); document.write( ":-) \n" ); document.write( " \n" ); document.write( " |
