Question

What is the area of triangle where each side is 6 long ?

Solve by Heron’s formula​

Answer 1

Answer:

the best way is 18

Step-by-step explanation:

6×3=18

Answer 2

Step-by-step explanation:

It's Given that, each side of triangle is 6.

Therefore, the semi perimeter is

$s = \frac{a + b + c}{2}$

here,

s = semi perimeter

a = length of side a

b = length of side b

c = length of side c

$s = \frac{6 + 6 + 6}{2 } \\ = \frac{18}{2} \\ = 9$

Using Heron's Formula

$area \: of \: triangle \: = \sqrt{s(s - a)(s - b)(s - c)} \\ area \: = \sqrt{9(9 - 6)(9 - 6)(9 - 6)} \\ = \sqrt{9(3)(3)(3) } \\ = 9 \sqrt{3}$

Therefore, the area of triangle using Heron's Formula is 9√3..²
