Question

Find the Area of an equalateral triangle of side 4 cm

Answer 1

Answer:

4√3 cm²

Step-by-step explanation:

we know that area of an equilateral triangle = $\frac{\sqrt{3}}{4} a^{2}$ where 'a' is the side of the triangle.

So area of triangle = √3 /4 × (4)^2

                               = √3 /4 × 16

                               = 4√3 cm²
