A chess board that has the shape of a square.A currency note which has the shape of a rectangle.Every 2D shape can be measured by its width and length.Ī few real-life examples of 2d shapes are given below:.Here are a few important notes that should be remembered while studying 2D shapes. The following table shows the formulas that are used to calculate the area and perimeter of a few common 2D shapes: 2D ShapeĪ = π × r 2, where 'r' is the radius of the circle and 'π' is a constant whose value is taken as 22/7 or 3.14 The perimeter of a 2D shape is the total length of its boundary. The area of a 2D shape is the space enclosed within it. Observe the properties of the given rectangle ABCD to identify it as a 2D shape. Some of the real-life examples of a rectangle are table tops, blackboards, cardboard, etc. All four sides are equal, i.e., side PQ = QS = RS = PRĪ rectangle is a 2D shape with four sides in which the opposite sides are equal and parallel, and all the four angles measure 90 ̊.Observe the properties of the given square PQSR to identify it as a 2D shape. Some of the real-life examples of a square are: a loaf of bread and a chessboard. The following figure shows the sides and vertices of a triangle.Ī square is a 2 dimensional shape with four equal sides and each angle is equal to 90˚. Some real-life examples of a triangle are traffic signs, pyramids, and nachos.
