Answers to Questions
What is the Pick Theorem?
Pick's theorem easily calculates the area of a polygon with \( b \) vertices built on a 2D grid of points with integer coordinates (points with equal distances). If all \( b \) vertices of the polygon are grid points and the polygon has \( i \) points inside itself then Pick's formula indicates that the polygon area \( A \) is equal to $$ A = i + \frac{b}{2} - 1 $$
How to calculate an area with the Pick Theorem?
The Pick formula requires only two parameters: the number \( i \) of interior points of the polygon and the number \( b \) of vertices of the polygon. Thearea \( A \) of the polygon is\( A = i + \ frac {b} {2} - 1 \)
Example: The polygon drawn below 
has 15 points inside the polygon (light gray), and 10 vertices (dark gray). Its area is therefore \( A = 15 + 10/2 - 1 = 19 \).
