yes
yes, i certainly can
how
Now, let  be the area of each rectangle shown above. Clearly, the area of the largest square is the sum of the areas of the two smaller squares and the two rectangles. In equation form, we have
.
Expanding the left hand side, we have
.
Subtracting x^2 + y^2 from both sides results to
.
Solving for  gives us
.
But  and  are the length and width of the rectangle, therefore, the area of any rectangle is the product of its length and its width.
