Answer 2

$\huge{\pink{\underline{\underline{Answer:-}}}}$

Given:

In equilateral triangle,

Length of three sides are equal to 23 cm

To find:

Perimeter = ?

Method:

Perimeter of equilateral triangle = 3a or a+b+c

As in equilateral triangle all sides are equal and addition of all sides is equal to perimeter

Therefore, perimeter of equilateral triangle is 23 cm

Extra points:

# In equilateral triangle, all sides are equal and internal angles are also equal to 60°

# Perimeter of equilateral triangle = 3a

# Area of equilateral triangle = √3/4 a²

where a is side of equilateral triangle
