What is Square Footage

This online calculator allows you to calculate the area of various geometric shapes such as Rectangle, Parallelogram, Circle, Sector of a circle, Triangle, Regular polygon, Ellipse, Trapezoid. For the convenience of calculations, you can select the unit of measurement (millimeter, centimeter, meter, kilometer, foot, yard, inch, mile). Also, the obtained result can be converted to another unit of measurement by selecting it from the drop-down list.

In order to convert from meters to square meters, you need to multiply the width in meters by the length in meters. The wall area calculator will help you calculate the wall area of a room or house, as well as floor and ceiling areas for rooms of various shapes and sizes, taking into account openings for windows and doors. The calculation of the area of the room is made in two ways, depending on whether the room has a strictly rectangular shape or not. This calculator will help you quickly cope with this task.

When calculating the area of a room of a complex configuration, first it is divided into simple geometric shapes - rectangles and triangles, then the area of each of the figures is calculated, and finally, the results obtained are summed up. We will use the most versatile method - triangulation. Its versatility lies in the fact that not every polygon can be split into rectangles, but any one can be split into triangles.

The calculator includes: Calculating the area of a circle: Through radius, diameter, circumference. Calculation of the area of a rectangle on two sides, along the diagonals and the angle between them. Calculation of the area of an ellipse along two semiaxes. Calculation of the area of a rhombus along the side and height, along two diagonals, along the side and the angle between the sides, along the side and the radius of the inscribed circle. Calculation of the area of a triangle, Calculation of the area of an equilateral hexagon, Calculation of the area of a trapezoid, Calculation of the area of a parallelogram.
