Question

find a b c if the perimeter of a triangle is 36 cm and its sides are in the ratio A B C is equal to 3 ratio 4 ratio 5​

Answer 1

Answer:

let, a = 3x

b= 4x

c= 5x

then, a+b+c= perimeter of the triangle

So, 3x+4x+5x=36

12x=36

x=3

Ans: a= 3*3 = 9cm

b= 4*3 = 12cm

c= 5*3 = 15cm

Answer 2

Perimeter = 36 cm

sides in ratio 3:4:5

Let the side be x

3x+4x+5x=36

12x=36

x=3

sides will be

3x=3*3=9

4x=4*3=12

5x=5*3=15
