Question

please answer this question with formula​

Answer 1

Step-by-step explanation:

A=30m B=40m C=50m

perimeter =A+B+C = 30+ 40+ 50 m=120m

semi perimeter =A+B+C/2= 120/2 = 60

S-A= 60-30=30m

S-B= 60-40=20m

S-C= 60-50=10m

Heron's formula =s(s-a) (s-b) (s-c)

=√60x30x20x10

=√2x3x10x3x10x2x10x10

=√2x3x10x10

=600m

length of altitude drawn on largest side

=600/50=12m
