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.
Square Area = a2 a = length of side       Calculating the Area of a Square     How to find the area of a square:     * The area of a square â¦ can be found by multiplying the base times itself. This is similar to the area of a rectangle but the base is the same length as the height.=s2 The area of a square is calculated by squaring the side length, because the two sides (length and width) are the same. For example: If the side of the square is 5 cm, â¦ the area is (5 cm)2 = 25 cm2.
