![]() ![]() 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.
