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.
In this example each grid square has a width of 1cm and a height of 1cm. In other words each grid square is one 'square centimeter'. Count the grid squares inside the large square to find its area.. There are 16 small squares so the area of the large square is 16 square centimeters.nswers to above example. First, work out the area of the main shape of the house â that is the rectangle and triangle that make up the shape. The main rectangle (B Ã C) 7.6 Ã 8.8 = 66.88m 2. The height of the triangle is (A â B) 9.7 â 7.6 = 2.1. The area of the triangle is therefore (2.1 Ã C) Ã· 2.
