Measurement of land is an important part of almost every aspect of life. We use it for many purposes, for instance to construct buildings and roads, to farm, to produce goods, and to manage our resources. It is the most basic and fundamental tool for the purpose of obtaining an accurate idea of the size and shape of an area.

The problem is that measuring land is a very difficult task. It has to be done in a way that is both accurate and convenient. The most common approach is to use a tool that is designed specifically for the purpose. There are many different types of tools, but the most common one is the pen and paper.
