Question

If the centroid of a triangle fomed by (3. xl. 41,5) and
(.-6) is (0, 1) then find any)?
Find the peruneter of a Inangle with venices 0.41 0.0) and​

Answer 1

Answer:

Let ABC be a triangle having A(0,4);B(0,0);C(3,0)  

Using distance formula, we get  

AB=  

(0−0)  

2

+(0−4)

​  

=  

16

​  

=4

BC=  

(3−0)  

2

+(0−0)

​  

=  

9

​  

=3

CA=  

(0−3)  

2

+(4−0)

​  

=  

25

​  

=5

Perimeter of △ABC=AB+BC+CA=4+3+5=12
