Question

Find the sides of equilateral triangle whose circumference is 18cm

Answer 1

Equilateral triangles are those which have all the sides of equal measure. It means 3 equal sides. Let s be the side of the triangle. Here, perimeter = 18 cm

So, Perimeter = 3 x s

18 = 3s

3s = 18

s = = 6

Hence, the length of each side of the triangle is 6 cm.
