The equations to find the areas would be:
A = W*(L - x)
A' = W*x
Where W is the width, L is the length, and x is defined by where she divides the rectangle.
So originally, we have a rectangle of length L and width W.
Let's assume that tina divides the length, by cutting "x" of the length to make one of the rectangles.
Then, we have two rectangles of width W, and one has a length of (L - x) and the other has a length of x. (A diagram of this can be seen below).
Then the area of these two rectangles will be:
A = W*(L - x)
A' = W*x
Now we want to see another way of dividing the rectangle, and well, we could also divide it along its width, and the calculations are exactly the same.
