Question

the shape of a field is equilateral triangle if it's sides are 120m each then find its area using Heron's formula ​

Answer 1

S=A+B+C/2=120+120+120=360
by heron's formula
area=underoot S(S-A)(S-B)(S-C)
area= underoot 360(360-120)(360-120)(360-120)
area=underoot 360×240×240×240
area=underoot 497664000
by taking square root
area= 70454.30m^2
