Let the common multiple of the given ratios be 'x'
Thus the ratio will now become 3x, 4x and 5 x.
Perimeter of a triangle is sum of all the sides of a triangle.
Summing up the ratios of the sides we get,
3x + 4x+ 5x = 60
12x = 60
x = 60/12
x= 5
 
Thus side with the ratio 3x measures, 15 cm,
Side with the ratio 4x measures, 20 cm and
Side with the ratio 5x measures, 25 cm.
