Date:2012-02-19 20:34:42 Perimeter of a triangle is 108 cm,its sides are in ratio 2:3:4,find its area? Since side of triangle are in ratio 2 : 3 : 4, so let the sides of triangle be 2x, 3x, 4x..........(1) Perimeter of triangle = 108 put value of sides from (1), we get 2x + 3x + 4x = 108 add like terms and we get; 9x = 108 divide both side by 9 and we get; x = 12 put the value of ' x ' in (1) and we get; side 1 = 2x = 2 * 12 = 24 side 2 = 3x = 3 * 12 = 36 side 3 = 4x = 4 * 12 = 48 Hope this will help you.
