If and only if you are working with a square, you get the square root of the number
Square meters of what? If you want the area in square meters of a rectangle, just multiply the length times the width (both in meters). To get square meters of other figures, other formulae are required.
look at the square and count
That is like asking how many yards in a gallon. There are no square meters in a meter, and no meters in a square meter.
measure in square meters, a paddock with four different sides
To work out square meters you need two dimension not just one length.
To find the area of an objet, which is measured in square units, multiply the length times width. For example, if the object is 9 meters long and 3 meters wide, the area is 27 square meters.
Doesn't work. Meters is distance only, square millimeter is a unit for area. They don't compare.
If it's square meters, you are only concerned with area, yes? In this case if it's a flat roof, it will be 5mx5.5m, (no leeway outside of the walls). 5x5.5 is 27.5m2.
meters times meters = square meters
About 1.3 square meters. (1.30064256 square meters).
one ton of sand covers about 100 square feet which is about 9.3 square meters.
144 square meters
