Question

find the area of an equilateral triangle
having side as 2^3 cm.​

Answer 1

Step-by-step explanation:

Given, side of an equilateral triangle is 2√3 cm.

Area of an equilateral triangle = √3/4 (Side)2

= √3/4 (2√3)2 = (√3/4) x 4 x 3

= 3√3 = 3 x 1.732 = 5.196 cm2

Hence, the area of an equilateral triangle is 5.196 cm2.

Answer 2

Answer:

Hence, value of area of equilateral triangle having side $2^3$ cm will be $16{\sqrt{3}} \:cm^2$

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 = $2^3$ 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,

$Area = \frac{{\sqrt{3}}}{4}\:side^2\\Area = \frac{{\sqrt{3}}}{4} \times 2^3 \times 2^3\\=>Area ={\sqrt{3}} \times \frac{8 \times 8}{4}\:cm^2\\Area =16{\sqrt{3}} \:cm^2$
