Question

Find the area of equilateral triangle having side 8 cm

Answer 1

Area = 1/2*base *height
         = 1/2*8 cm*8 cm
         = 1/2*64 cm
         = 64/2 cm
         = 32 cm square

Hope this helps you...

Answer 2

Answer:

Hence, value of area of equilateral triangle having side 8 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 = 8 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,

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