Technically, the answer is "un-defined" or un-answerable. They define 2 different types of measurement.A "meter" is a measurement of length, while a square meter is a measurement of area.Think of it in terms of the shape of a square that is 1 meter x 1 meter x 1 meter x 1 meter. You can define the perimeter length (which is what you might be asking for), and that = 4 meters (each of the sides of the square added together). The area of the square is 1 square meter, which you get by multiplying 2 sides of the square together, which in this case is 1 meter multiplied by 1 meter = 1 sq/meter.
Light intensity or irradiance
A square 1 meter long and 1 meter wide is 1 square meter. 1 square meter equals 1.19599 square yards 1 square meter equals 10.76391 square feet
Half Square meter is twice as big as half a meter square.
1 yard = .9144 meter, therefore 1 square yard = .83612736 square meter. In other words, 1 square meter = 1.19599005 square yard
The lux is the SI unit of illuminance, and is equal to 1 lumen per square meter.

To calculate lux level in a room, you need to measure the illuminance using a lux meter. The lux meter records the amount of light falling on a surface per unit area. By taking measurements at different points in the room and averaging them, you can determine the overall lux level.
Apparently Lumen's :S
The second.I see the "second" as a measure of time, not light.LUX, Lumen or Candela do ring a bell and something like watt per square meter..Yes the S.I. unit measure of light is a limen (lm) .lumen (lm)The SI derived unit for measuring the luminous flux of light being produced by a light source or received by a surface. The luminous intensity of a light source is measured in candela. One lumen represents the total flux of light emitted, equal to the intensity in candela multiplied by the solid angle in steradians (1/(4pi) of a sphere) into which the light is emitted. Thus the total flux of a one-candela light, if the light is emitted uniformly in all directions, is 4pi lumen.
Light intensity or irradiance
Irradiance is the term used to describe how many watts of power fall across one square meter of area. It is often measured in units of watts per square meter (W/m²).
You cannot
define the linermeter
The square root of meter squared is meter.
A square 1 meter long and 1 meter wide is 1 square meter. 1 square meter equals 1.19599 square yards 1 square meter equals 10.76391 square feet
1x1 meter is a square meter.
