Answer» LET the sides of the TRIANGLE be a, b & c RESPECTIVELY. $(\because a:b:c = \;\frac{1}{2}:\frac{1}{3}:\frac{1}{4})$ ⇒ a = x/2, b = x/3, c = x/4 We KNOW that, Perimeter of the triangle = a + b + c $(\Rightarrow 78 = \frac{x}{2} + \frac{x}{3} + \frac{x}{4})$ $(\Rightarrow 78 = \frac{{6x + 4X + 3x}}{{12}} = \frac{{13x}}{{12}})$ ⇒ x = 72 cm ∴ Length of the smallest side = c = x/4 = 72/4 = 18 cm |
