Question

Find the area of the triangle whose sides are 42 cm, 34cm and 20 cm in Lengthe Hence find the height corresponding to the longest side​

Answer 1

19.76 cm hope it will help you

Answer 2

Answer:

A =√{s(s-a)(s-b)(s-c)}

s=(42+34+20)/2=48

A=√{48×(48-42)(48-34)(48-20)}

=√(48×6×14×28)

=6×7×8=336

height:=h

(1/2)×42×h=336

h=336×2/42=16
