Question

The sides of a triangle are in the ratio 1 : 2 : 3. if perimeter i 36 cm, find its sides
Explain with step by step solution...​

Answer 1

Answer:

HERE IS THE SOLUTION ↓↓↓

--------------------------------------

Ratio:- Side 1 : Side 2 : Side 3 = 1:2:3

Define x:-

let x be the constant ratio

Ratio:- Side 1 : Side 2 : Side 3 = 1x :2x :3x

From equation:

Perimeter = Side 1 + Side 2 + Side 3

36 = 1x + 2x + 3x

36 = 6x

6x = 36

x = 36 ÷ 6

x = 6 cm

Find the sides:

Side 1 = x = 6 cm

Side 2 =2x + 2(6) = 12 cm

Side C = 3x = 3(6) = 18 cm

★Answer: The sides are 6cm, 12cm and 18 cm
