The word 'perimeter' is derived from the Greek word 'Perimetron.' “Peri” is a Latin word that means 'about,' and 'Metron' is a Greek word that means “measure.”Īdding up the lengths of all the sides of a form or measuring the outer limit of a shape or object, yields the perimeter of that shape or object. The amount of space in a backyard that needs to be planted with flowers, and so on. The amount of space in a room's floor that needs to be covered with tiles. Utilisation of the concept of area to determine the amount of space that needs to be painted on a wall. There are many real-life examples also, such as: Suppose two squares have sides s and s1, so the areas of the two squares will be equal is s = s₁ If two figures have a similar shape it is not necessary that they have equal area unless and until their dimensions are equal. Suppose if you want to paint the rectangular wall of your house, you need to know the area of the wall to calculate the quantity of the paint required to paint the wall and the cost of painting. Let's assume any blue square occupies 9 square units, which means that the square has a surface area of 9 square units.Įg. The total number of unit squares included within a figure is equal to the figure's area in square metres. Using a square grid paper, the concept of locating an area may be simply applied. For instance, the area of the square differs from the area of the rectangle.Įg.1. The area of any shape depends upon its dimensions. Hence, the area of a shape is calculated in square units (sq units). The actual area of a shape, an object, or a flat surface is defined by the total number of square units that can be included within it. Or we can say, the quantity of space occupied by any shape, item, or flat surface is defined as the area of the shape, object, or flat surface. The area is the measurement of the space occupied by any two-dimensional geometric shape. The ways to measure the area and perimeter are completely different. The area is the space occupied by any two-dimensional geometric figure and the perimeter is the distance around the shape or you can say boundary of the shape. So here on this page, we will study Maths area and perimeter formulas associated with different shapes. Hence every shape has a different area and perimeter, based on its measurements. Every shape has its unique properties and measurements. We see many shapes around like squares, rectangles, circles, polygons, etc. We come across many shapes whose required space and distance around them have to be calculated and this is termed as the area and perimeter of the shapes. Area and volume are the two important concepts used in our daily life. We calculate different terms associated with the shapes, like length, width, height, area, perimeter, volume, etc. Geometry deals with plane shapes and solid shapes. As we know that geometry is the study of shapes.
