Question

the side of a triangle are in the ratio 5:6:13 if it's perimeter is 48cm it's side will be

Answer 1

Let the sides be 5a, 6a and 13a

Perimeter = Sum of Length of all sides

=> 48 = 5a + 6a + 13a

=> 48 = 24a

=> a = 2

First side = 5 × 2 = 10 cm

Second side = 6 × 2 = 12 cm

Third side = 13 × 2 = 26 cm

Answer 2

let 1st side=5x
2nd side=6x
3rd side=13x
a/q
24x=48
x=2
1st side= 5*2=10
2nd side =6*2=12
3rd side =13*2=26
