You measure area in square units because its convenient for the majority of maths you use (if drawing circles was 'cheaper' than drawing two perpindicular lines or if it made the maths simpler then we'd probably do that instead).

**What units are used to measure area?** In the International System of Units (SI), the standard unit of area is the square metre (written as m^{2}), which is the area of a square whose sides are one metre long. A shape with an area of three_square metres would have the same area as three such squares.

**How do you find out the area of a quadrilateral?** For squares, multiply one side by itself to get the area. If you have a parallelogram, multiply the diagonals and divide by 2 to get the area. To find the area of a trapezoid, add the base and the height together, and divide that number by 2 times theheight.

**What is the formula of total surface area of cylinder?** The general formula for the total surface area of a cylinder is T. S.A.=2πrh+2πr2.

**What is the measurement?** In the classical definition, which is standard throughout the physical sciences, measurement is the determination or estimation of ratios of quantities. Quantity and measurement are mutually defined: quantitative attributes are those possible to measure, at least in_principle.
