# The Farmer in the Dell

Pro Problems > Math > Geometry > Rectangles and Squares## The Farmer in the Dell

Farmer Dell has a field that is shaped like a letter L, and he wants to divide it into three parts, as shown below:

The region in the upper right corner has a perimeter of 140 yards. The regions in the upper left corner and the lower right corner both have perimeters of 180 yards. He originally had enough fencing to enclose the two top regions, and now he needs an extra 140 feet of fencing to complete the job.

What is the total area of his field?

### Overlapped Rectangles

Two rectangles are overlapped on a corner as shown in the image. The overlapped region is a square. The length of one rectangle is twice the length of the other, and its width is half the width of the other.

If we consider the rectangles as a single geometric figure, its outer perimeter is 768 units, and its area is 8415 square units.

The perimeter of the first rectangle is 312 units.

Find the area of the overlapped square, given that all the side measures are integers.
