Answer 1

The area of an equilateral triangle with perimeter of 36 centimetres is 62 centimetre squared.

What is an equilateral triangle?

An equilateral triangle is a triangle that has all its sides and angles equal to each other.

Therefore,

perimeter = 36 cm

Each side = 36 / 3  = 12 cm

Hence,

area  = 1 / 2 bh

h² = 144 - 36

h = √108

h = 10.3923048454

h = 10.4

Hence,

area = 1 / 2 × 12 × 10.4

area of the equilateral triangle = 124.8 / 2

area of the equilateral triangle = 62.4

area of the equilateral triangle = 62 cm²
