Question

the side of a triangle are in the ratio 2:3:4 if the perimeter is 72 cm. find its side

Answer 1

Let the sides be 2x, 3x, and 4x.
2x + 3x+ 4x = 72
9x = 72
x = 8

sides = 2x = 2(8) = 16
3x = 3(8) = 24
4x = 4(8) = 32

Sides are 16 cm, 24 cm, and 32 cm.

Answer 2

Let the sides of triangle be 2x, 3x and 4x.

Perimeter of triangle = 72 cm

A/q,

Sum of all sides = Perimeter of triangle.

➡ 2x + 3x + 4x = 72

➡ 9x = 72

➡ x = 72/9

➡ x = 8

Sides of triangle :-

➡ 2x = 2(8) = 16 cm

➡ 3x = 3(8) = 24 cm

➡ 4x = 4(8) = 32 cm.

Hope it will help you !!!
