Question

The area of an equilateral triangle with side 4 cm.

Answer 1

You measure the area of a triangle with the base multiplied by the height divide by 2.

Answer 2

4
`√(3\\)` ≈ 6.93 cm²

Explanation:

The area (A) of an equilateral triangle is calculated as

A =
`(s^2√(3) )/(4)` ← s is the side length

here s = 4, thus

A =
`(4^2√(3) )/(4)`

=
`(16√(3) )/(4)`

= 4
`√(3\\)` ≈ 6.93 cm²
