Meters or yards if it's the school library, in the same building or on the same campus
as the classroom.
Kilometers or miles if it's simply the municipal library, in the same city as the classroom.

A metre is most appropriate.

Do it in feet usually but do it in meters
Meters, or kilometers, depending on the distance. yards, or miles, depending on the distance.
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.
Meters are used for measuring distance. For classroom lenght use meter (m). For classroom floor space use square meter (m*m or m^2). For classroom volume use cubic meter (m*m*m or m^3).

Identify the SI until you would use the measured the width of your classroom
METERS!!!The unit of measurement you would use to measure the width of your classroom is meters.
in feet
I would use a yardstick, a foot ruler, a tape measure, a meter stick, or a laser rangefinder to make the measurement. After I knew the distance, I could convert it into any convenient unit in order to describe it or report it to others. The most convenient metric units would be either meters or centimeters.

Do it in feet usually but do it in meters
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.
With a tape measure or a yard stick.

Meters
A stapler
I would use a tape measure. This would require one person to help me, since the tape measure would have to be held at both ends. Even if the classroom is longer than the tape measure, I could just mark the full extent of the tape and then measure again from there.
