I recently learned about the shoelace formula and I was quite smitten by it. 😍 The shoelace formula allows you to calculate the area of a simple polygon from the coordinates of its vertices. It relies on 2x2 determinants, so executing this formula is quite quick! To understand why the shoelace formula works, imagine each edge of your polygon as one leg of a trapezoid that extends down to the x-axis. The signed areas of these trapezoids will then add up to the area of your polygon. The sign of e
