Question

The sides of a triangle are 42 CM 34 cm and 20 CM calculate its area and the length of the height on the longest side

Answer 1

Area of Triangle using Heron's Formula=
A+B+C by 2=42+34+20/2
= 48(s)
Therefore Root s(s-a)(s-b)(s-c)
=2282.541
Longest side= Hypotenus
Using Pythagorus Theorum
half into l X B= Area
Therefore H= 108.692
