Question

Q11.Find area of equilateral triangle having side 2 cm.​

Answer 1

Answer:

8cm area of equilateral triangle

Answer 2

Answer:

Hence, value of area of equilateral triangle having side 2 cm will be ${\sqrt{3}}\:cm^2$

Step-by-step explanation:

In context to question asked,

We have to determine the value of area of equilateral triangle.

As per data given in the question,

We have,

Side of equilateral triangle = 2 cm

As we know that,

Equilateral triangle is that particular triangle whose all sides are equal.

As we have,

Formula for finding the area of equilateral triangle -

$Area = \frac{{\sqrt{3}}}{4}\:side^2$

So, for determining the value of area of equilateral triangle, we will put the value of side of triangle in above formula,

So, we will get it as,

$Area = \frac{{\sqrt{3}}}{4}\:side^2\\Area = \frac{{\sqrt{3}}}{4} \times 2 \times2 \\=>Area ={\sqrt{3}}\:cm^2$
