Find the length of two of the sides...the length of a side is:

L^2=(x2-x1)^2+(y2-y1)^2

So if we first look at the two "bottom" points...we get:

b^2=(-1--3)^2+(-2--4)^2

b^2=2^2+2^2

b^2=4+4

b^2=8

b=√8

Now if we look at the two "left" point that make of a side we have:

s^2=(-3--6)^2+(-4--1)^2

s^2=3^2+(-3)^2

s^2=9+9

s^2=18

s=√18

So the area of this rectangle is bs so

A=√8√18

A=√144

A=12 u^2
