Question

Find the area of a triangle whose sides are 150, 120 and 200cm using Heron's formula.

Answer 1

Step-by-step explanation:

S=(150+120+200)/2

S=470/2=235

Area=√s(s-a)(s-b)(s-c)

=√235(235-200)(235-150)(235-120)

=√235×35×85×115

now plz calculate ...

Answer 2

Answer:

470cm^2

Step-by-step explanation:

a=150cm

b=120cm

c=200cm

area=

$\sqrt{(s - 150) (s - 120)(s - 200)}$

s=150+120+200/2

$= > 235$
