Question

triangle ABC is an equilateral triangle. is AB=30cm ,then find the area of triangle ABC using herons formula.​

Answer 1

Answer:

as the given triangle is equilateral triangle

therefore all sides are equal to 30cm

s=a+b+c/2

s=90/2

s=45

using herons formulae

$\sqrt{s(s - a)(s - b)(s - c)}$

therefore

whole root. 45 *15*15*15

=225√3

therefore area of triangle is equal to 225 root 3

hope it helps u dear
