Question

sides of a triangle are 120 m ,170 mand 240 m. if the area of the triangle is (9000 m) 2 then the height of the triangle with the base 250 is ​

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 the 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
