Geometer's calculations refer to the mathematical calculations used by geometers, which are professionals who specialize in the study of geometry. Geometry is a branch of mathematics that deals with shapes, sizes, and relative positions of figures and with properties of space. Geometer's calculations involve the use of formulas to calculate the area of shapes, such as circles, triangles, and rectangles. The term 'AREAS' is an acronym for the five letters A-R-E-A-S, which stands for 'Area, Radius, Edge, Angle, and Side'.
