with a tape measure

To calculate the area of a rectangle, you multiply the length times the width. To calculate the area of a square, you multiply one side times another side. To calculate the area of a circle, you multiply the diameter times pi (that's 3.1416). To calculate the area of a triangle, you multiply the height times the base, and divide by 2.
