It depends on what information you do have about the triangle.
There are different equations depending on whether you know the lengths of three sides, the lengths of two sides and the measure of the included angle, the length of one side and the perpendicular distance to the other vertex (base and height).
1 square metre = 10.7639104 square foot
They are: 1 square meter = 1*1 = 12 meters and 1 cube meter = 1*1*1 = 13 meters
Conversion: cm2 x 0.0001 = square meters
6metres x 8metres = 48 square metres
multiply the width by the breadth

To calculate the price per square meter, divide the total price by the total number of square meters. For example, if a piece of cardboard with an area of 10 square meters cost 5 dollars, the price per square meter would be (10 m2)/($5), which comes out to be 50 cents per square meter.

That would depend what information you are given. The cost of floor tiling is often already expressed per square meter. If you know the total cost of a certain floor, you can divide by the area to get the cost per square meter.
Square feet x 0.0929 = square metres
there are 54 bricks per square meter
A square meter of water would not be measured in gallons, as gallons are a measure of volume, while square meters are a measure of area. It would depend on the depth of the water in the square meter area to calculate the volume in gallons.
