construct a triangle ABC whose perimeter is 14cm and sides are in the ratio of 2:3:4 .

Let the 3 sides of the Triangle be 2x, 3x and 4x

14 = 2x + 3x + 4x

14 = 9x

x = 14 / 9

Therfore, x = 1.5cm

2(1.5) = 3.0cm

3(1.5) = 4.5cm

4(1.5) = 6.0cm

Now you have the length of the sides:

AB = 3.0cm

BC = 4.5cm

CA = 6.0cm
