Question
A piece of wire is 36 cm long. What will be the length of each side if we form an equilateral triangle
Advertisements
Solution
Given the length of the wire = 36 cm
When an equilateral triangle is formed out of it, its perimeter = 36 cm
i.e., side + side + side = 36 cm
3 × side = 36 cm
side = `36/3`
= 12 cm
One side of an equilateral triangle = 12 cm
