Question

two side of a triangular field 85 M and 154 M effectively and its perimeter is 324 M find the perpendicular from the opposite angle on the side 154M

Answer 1

Hii...

a1+a2+a3=324

85+154+a3=324

239+a3=324

a3=324-239==85

semiperimete (s)=324/2=162

Area=√s(s-a1)(s-a2)(s-c3)

====√162*(162-85)(162-154)(162-85)

====√162*77*8*77

=====√77*77*16*81

====77*4*9

====77*36

=====2772


area==1/2*base*height




2772==1/2*154*height


height=2772*2/154

========18*2==36
