97.5 in wrong!
The area of a polygon can be calculated by finding the area of the rectangle that encloses the polygon, and then subtracting the areas of any overlapping shapes.
In this case, the rectangle that encloses the letter L outline has a height of 13 and a width of 15. Therefore, the area of the rectangle is 13 * 15 = 195 square units.
Since the letter L is half of a rectangle, its area is half of the area of the enclosing rectangle. Therefore, the area of the letter L is 195 / 2 = 97.5 square units.
