Question

Find the area of equilateral triangle who dides length a=b=c=4cm using herons formula

Answer 1

Step-by-step explanation:

let

sides of equilateral triangle =a+b+c/2

therefore we get

4+4+4/2

12/2

=6

Answer 2

Answer:

Sides of equilateral triangle = 4 cm

Herons formula = (a+b+c)/2 = s

(s(s-a)(s-b)(s-c))^1/2

4+4+4/2=6

6(6-4)(6-4)(6-4)^1/2=48^1/2=> 3^1/4
