Question

each side of an equilateral triangle measures 8cm it's area is
​

Answer 1

Step-by-step explanation:

According to the Heron's formula, Area (A) of the triangle having sides a,b,c units is

A=

s(s−a)(s−b)(s−c)

where

s=

2

a+b+c

For the given triangle,

a=b=c=8cm

s=

2

8+8+8

=12

A=

12(12−8)(12−8)(12−8)

A=

3×4×4
