Question

The side of an equilateral triangle is 2/3 cm. The perimeter of the triangle is.... *

Answer 1

Answer:

All side of equilateral triangle is same

i. e 2/3cm

perimeter =sum of all side of triangle

perimeter =(2/3+2/3+2/3)

perimeter =3x2/3

perimeter =2cm

Answer 2

Answer :

• 2 cm

Given :

• Side of an equilateral triangle = 2/3 cm

To find :

• the perimeter of the triangle

Solution :

⇒ Let's find the perimeter of the triangle.

$\sf \longrightarrow Perimeter \: of \: Equilateral \: Triangle = s + s + s$

Here,

• s = 2/3 cm

$\sf \longrightarrow Perimeter \: of \: Equilateral \: Triangle = s + s + s$

$\sf \longrightarrow \dfrac{2}{3} + \dfrac{2}{3} + \dfrac{2}{3}$

$\sf \longrightarrow \dfrac{2 + 2 + 2}{3}$

$\sf \longrightarrow \dfrac{6}{3}$

$\cancel { \sf \longrightarrow \dfrac{6}{3} }$

$\longrightarrow \sf 2$

$\longrightarrow \sf 2 \: cm$

• Therefore, the perimeter of an equilateral triangle with the side of 2/3 cm is 2 cm.
