Answer 1

Answer:

I suggest you to use Formula of triangle

It is of class 10

Answer 2

Answer:

12cm

Step-by-step explanation:

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)²

    = √16

     =4

BC=√ (3−0)²+(0−0)²

    =√9

    = 3

CA=√(0−3)²+(4−0)  ²

    =√25

    = 5

Perimeter of △ABC=AB+BC+CA

                                =4+3+5

                                =12cm is the answer.
