First plot the points and see what you've got.

Define a couple of extra points that will help simplify the solution.
X at (4,4)
Y at (-1,-1)

Now we can find the areas of the individual triangles and square and add them together.
Area of a square is s*s where s is the side length.
Area of a triagle is half the product of base and height.

Square BXDY :
Triangle XCD :
Triangle DEY :
Triangle EAB :
Now add all of the areas,
