What is the area, in square units, of the square with the four vertices at A(0,0), B(-5,-7), C(2,12), and D(7,5)?

Definitely NOT  a square  !!!

 

 

Easiest  way to  calculate   [ABCD     :]

 

Find the area of rectangle EHFB

 

From this  subtract  areas of

Right triangles   BEC , CFD , AGD  and Trapezoid  AGHB
