Question

The area of an equilateral triangle is 900root3m square. find it's perimeter using herons Formula​

Answer 1

Step-by-step explanation:

Areaof equilateral triangle

$\frac{ \sqrt{}3a {}^{2} }{2}$

900√3=√3/4×a^2

(900√3×4)/√3=a^2

3600=a^2

60=a

perimeter=3a

=3×60

=180

Answer 2

Answer:

herons formula is √S(S-A)(S-B)(S-C)

By this the answer will be 180m
