The sides of a triangle are in the ratio 1/3 : 1/5 : 1/4 and its perimeter is 188 cm. The length of the longest side is :

Ratio of the sides 1/3 : 1/5 : 1/4 = 20:12:15

let the sides are 20x, 12x and 15x

Perimeter of the triangle is 188 (Given)

Therefore, 20x+12x+15x = 188

i.e, x = 4

Therefore the largest side is 20 * 4 = 80 cm
