Question

Size of triangular 112m,170 M and 250 m find its area and height of the triangle its base is 250 m

Answer 1

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
