Ontario Curriculum Expectation:
6.E2.1 measure length, area, mass, and capacity using the appropriate metric units, and solve problems that require converting smaller units to larger ones and vice versa.
We use millimetres (mm), centimetres (cm), metres (m) and kilometres (km) to measure length or distance.
When these units are used to measure area, they are changed to square units.
The area of a square metre (m2) is the area of a square with a side length of 1 m.
A full-sized basketball court is about 440 m2.
