Here you can calculate the surface area of any rectangle, square, rhombus, triangle, circle or parallelogram by simply providing Mr. Calculator with the required measurements! This project was not created with the intention of making it easier to cheating on a test but instead as a fun teacher-student tool to learn about surface area and to be used as a double checker.
