A farmer should know the size of his fields

A modern farmer should have regular- shaped fields, with square corners. That is, corners that make right angles.


These two corners are not square. They do not make right angles.


A square corner. It makes a right angle.

A corner of your booklet is a square corner because it forms a right angle.
Farmers should nowadays make all their fields with square corners.


Fields with square corners

Most modern fields have the shape of a rectangle. A rectangle is a field with 4 sides and 4 square corners. Your booklet is a rectangle, because it has 4 sides and 4 square corners.

The 2 bigger sides are called the length.

The 2 smaller sides are called the width.

When the length and the width are the same, the rectangle is called a square.

A good farmer should know the length and width of his fields. To know the length and width of a field the field must be measured.

Measuring the length or width of a field means knowing how many metres there are in this length or width.
