Question

the sides of a triangle are in the ratio 5:12:13 and it's perimeter is 150cm . find the sides of a triangle.

Answer 1

5x+12x+13x=30x=150cm
So, x=5cm

1. 25cm
2. 60cm
3. 65cm

Answer 2

let the sides be = 5x , 12x , 13x
perimeter of a triangle = side +side+ side
= 5x +12x +13x= 30x = assumed perimeter
real perimeter= 150 cm
sides = real perimeter = assumed perimeter
= 150 cm =30x
= 5=x
5x = 25 cm
12x = 60 cm
13x = 65 cm
hope this helps
