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.
Area of the rectangle = 4 Ã 2 = 8 cm2 We need 8 one-centimetre squares to make a rectangle 4 cm long and 2 cm wide. The area of the rectangle is 8 cm2. Area of rectangle = Length Ã Breadth Area of square = Length Ã Length. Find the area and perimeter of a rectangle with a length of 6 cm and a breadth of 4 cm.Area = Length Ã Breadth = 6 Ã 4 = 24 cm2 Perimeter = 2 Ã Length + 2 Ã Breadth = 2 Ã 6 + 2 Ã 4 = 12 + 8 = 20 cm.rea of rectangle = Length Ã Breadth Area of square = Length Ã Length. Find the area and perimeter of a rectangle with a length of 6 cm and a breadth of 4 cm.
