Question

The sides of a triangle are in the ratio 3:4:5. If the perimeter of the triangle is
36 cm, find the length of the three sides of the triangle.​

Answer 1

Step-by-step explanation:

A.T.Q(According to the question)

3:4:5=36 cm (let 3:4:5 be 3x,4x,5x)

3x+4x+5x=36 cm

12x=36 cm

x=36/12

x=3

3x=3(3)=9

4x=4(3)=12

5x=5(3)=15

Verification

Perimeter of triangle=side 1+side 2+side 3

Perimeter of triangle=9+12+15

Perimeter of triangle=36 cm
