Question

Find the perimeter of the Equilateral triangle whose side is 6cm​

Answer 1

Answer:

18 cm

Explanation:

Equilateral triangle is a triangle with equal sides .

If the side of equilateral triangle is 'a'

then perimeter of equilateral triangle = sum of the sides of the triangle

                                                              = a + a + a(∵all of its sides are equal)

                                                              = 3a

So, the perimeter of equilateral triangle is '3a'

now let us apply this formula .

= 3×6 cm

=  18 cm
