Question

Find the areacof a traingle of sides 14 cm , 15 cm , 16cm . Also , find the length of the perpendicular form the vertex opposite sides of length 15 cm . plz guys answer fast if answer correct i will follow you plz​

Answer 1

Given sides of triangle

a=13,b=14,c=15

Semi-perimeter s=

1/2 (a+b+c)= (13+14+15)/2=21

Area, A =

_/s(s−a)(s−b)(s−c)

A= _/21(21−13)(21−14)(21−15)

A=84 cm ²

In /_\ RSQ

RQ²=RS²+SQ²

15²=RS²+7²

225=RS²+49

225-49=RS²

176=RS²

_/176=RS

4_/11=RS

Hope it helps you.
