How to calculate the area of a field

19. To calculate the area of a field with right angles at the comers, multiply the length by the width of the field.

Example: a field is 100 metres long and 100 metres wide; its area is 100 x 100 = 10000 square metres (m2).

A square metre is a square measuring 1 metre In length and 1 metre in width.

One hectare = 10 000 m2.

Example: a field is 200 metres long and 50 metres wide; its surface is 200 x 50 = 10000 m2.

It is also 1 hectare.

A field which is 71 metres long and 71 metres wide, has an area of 71 x 71 = 5041 m2.

A field which is 100 metres long and 50 metres wide, has an area of 100 x 50 = 5 000 m2.

These are both fields of half a hectare.

Before you put your stakes along the boundary of the field, you must ask permission to cultivate the field according to the local laws and customs.
