$\bigstar \Huge\bold{\color{red}{\mathtt{ \: Answer}}} \star$

Given :-

• Ratio = 2:3:4
• Perimeter = 63 cm

To find :-

• Length of each side

Analysis:-

• First, make ratio in x form.

• Second, Make eqation from it.

• Third, find the value of x & Put it in all the ratio and then find value of each side.

Making a equation:-

⟹ 2x + 3x + 4x = 63

⟹ 9x = 63

⟹ x = 63/9

⟹ x = 7cm

Finding all sides of triangle :-

⟹ 2x = 2 × 7 = 14 cm

⟹ 3x = 3 × 7 = 21 cm

⟹ 4x = 4 × 7 = 28 cm

Therefore, all sides are 14cm, 21cm, 28cm.
