Question

خ
the area of triangle whose side are 120cm,170cm,250cm​

Answer 1

Answer:

S = (a+b+c) /2

=(120+170+250)/2

=540/2

=270

Area = under root s ( s-a) (s-b) (s-c)

=under root 270(270-120)(270-170)(270-250)

=under root 270*150*100*20

=under root 81000000

=9000

Therefore area of the triangle is 9000

Area of triangle =1/2*base * height

9000 =1/2*250*height

9000=125*height

Height =9000/125

Height =72
