The metric unit of the meter would be the appropriate measure of the area of classroom. Calculating area involves multiplying the length (in meters) of the classroom's length and width. Area of the classroom would be in square (^2) meters.
Most common household furniture would be practically measured in centimeters (metric) or inches (English); the most common reason for measuring furniture is estmating its fit within a floor space (or a storage area).

Square centimeters
The surface area is measured in square units
The square meter.
metres
centimeter
Metres, to measure its length or width, square metres to measure its area.
yeah ofcourse what kind of question
if you are after a metric measurement than millimetres^2
It depends on what you mean by size: its length, volume, surface area or even its mass.
no, Acres is an Imperial Unit for the measure of area. The metric unit for area is the square meter.
If you were measuring the whole of the classroom, you would most likely measure area, that is, of the floor space, or volume, that is, of the entire room. Therefore, you would be unlikely to measure simply the length of one side of the room.
Either the Imperial or metric system can be used to measure area (or anything else).
in feet
Square centimetres: unless I was in production in which case square millimetres.
