I would use dekameters (dkm or dam) because a dekameter is a 10 meters, so obviously, the school is large, therefore, a dekameter (10 ms) would be perfect. Hectometers are too much and kilo is impossible.

I don't think the decametre ("c" not "k") is one of the SI's 'Preferred Units'. The Hectometre (ha) - to stick to the proper spellings of these French words - is used in agriculture and forestry to replace the acre; and the sq. km is used generally for geographical areas; but the appropriate unit for something like a school is the square metre.
The metric system generally is not anthropocentric; and its SI development the ISO intends us all to use come what may, is even less so, but like it or not, we all have to be familiar with the SI version.
The easiest way - is to get into the habit of turning off equipment that's not in use !
Because you ran out of yards?

no you use a stopwatch to measure elapsed time.

feet
Meters (m) for distances, square meters (m2) for the area and cubic meters (m3) for the volume.
You could use yards to measure a building, but it is more common to do it in feet or in metres.
Metres.
you can use metres
The most appropriate unit of measure to use for measuring a 10-story building would be feet or meters. Each story of a building is typically around 10 feet high, so a 10-story building would be approximately 100 feet tall. Using a unit of measure like feet or meters allows for a more precise and accurate measurement of the building's height.
You could use a long tape measure or a laser measure device.You could use a long tape measure or a laser measure device.

You could use the centimeter (cm) or meter (m) unit to measure the length of a desk at school.
You would use mm. For the same reason you use feet instead of miles to measure the height of a building.
yard stick
use a ruler lol
