Question

The area of an equilateral triangle with side 4 cm.

Answer 1

Answer:

4$\sqrt{3\\}$ ≈ 6.93 cm²

Step-by-step explanation:

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

A = $\frac{s^2\sqrt{3} }{4}$ ← s is the side length

here s = 4, thus

A = $\frac{4^2\sqrt{3} }{4}$

   = $\frac{16\sqrt{3} }{4}$

   = 4$\sqrt{3\\}$ ≈ 6.93 cm²

Answer 2

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