A quick and simple tool to draw and calculate areas of quadrilaterals.

Calculate area of irregular quadrilateral area with several types of inputs. Four sides and a angle or diagonal are required. Also learn how to calculate.

The method of calculation for quadrilaterals is triangulation, which requires you to know the lengths of one of the two diagonals.

This area calculator determines the area of a number of common shapes, including rectangle, triangle, trapezoid, circle, sector, ellipse, and parallelogram.

A calculator for an area of irregular quadrangles for which the only lengths of the sides are known. So, I've decided to make this joke calculator.
