What is the area of triangle ABC with vertices A(x¹,y¹), B(x²,y²)and C (x³,y³)

Explanation:

Given

Required

Determine the area

The area of a triangle is :

By substituting values for the x and y coordinates of A, B and C;

We have:

So:

For instance

The area is:

a saline water is fed to a reverse osmosis unit at flow rate o rotameter connected to reject (retentate) line reads 8 installed in reject and permeate line reads 15.2 milli siemens/cm and 300 micro siemens/com respectively.
