Hi,



A rectangle has a length of 14 inches more than three times its height. 

If the perimeter of a rectangle is 396 inches, find its dimensions.

 P = 2L  + 2H

 P = 2(3x+14) +2x = 396

        8x + 28 = 396

        8x = 368

         x = 46, the height.  The width is 152.

  2·46 + 2·152 = 396
