There are a variety of modern definitions of economics, some reflect evolving views of the subject or different views among economists.
So the area of the square is 7 x7 = 49 cm^2 and the perimeter of the square is 7 x 4 = 28 cm. And in example 1 you have a square of side length 8cm and you need to work out the area and perimeter of the square. So the area of the square is 8 x8 = 64 cm^2 and the perimeter of the square is 8 x 4 = 32 cm.
Multiply the area in square feet by 0.09290304. The result is the area expressed in square meters. For example, the 168-square-foot room from the previous example measures 168 * 0.09290304 = 15.60771072 square meters. For most purposes, rounding your result to hundredths -- 15.61 square meters -- is sufficient.ultiply the area in square feet by 0.09290304. The result is the area expressed in square meters.
