Question

the perimeter of a triangle is 36 cm and its sides are in ratio ratio B ratio C is equal to 3 ratio 4 ratio 5 then find the sides ABC​

Answer 1

perimeter of triangle = 3x+4x+5x = 36

12x = 36

x = 3

sides are 3 x 3 =9

4 × 3 = 12

5×3 = 15

Answer 2

let the ratio be x.

A/Q

A + B + C = 36

3x + 4x +5x = 36

12x = 36

x = 36/12

x = 3

A= 3x = 3 × 3 =9

B = 4x = 4×3 = 12

C= 5x = 5 × 3 = 15 ANS
