![]() ![]() The perimeter of a wheel/circle (its circumference) describes how far it will roll in one revolution. A calculated perimeter is the length of fence required to surround a yard or garden. The perimeter of a circle or an ellipse is called its circumference.Ĭalculating the perimeter has several practical applications. The unit of the perimeter is in cm, mm, m, km etc.Perimeter is the distance around a two dimensional shape, a measurement of the distance around something the length of the boundary.Ī perimeter is a closed path that encompasses, surrounds, or outlines either a two dimensional shape or a one-dimensional length. The perimeter of the rectangle is obtained by adding all the sides of a rectangle. Perimeter : The perimeter is the total distance along the boundary of a closed figure. The unit of area is in square units like sq.cm, sq. The area of the rectangle is obtained by the product of the length and breadth of the rectangle. Step 3: Write the perimeter in linear units.Īrea : The area is the space occupied or enclosed by a closed shape. Step 3: Sum will be two times the length and two times the breadth of a rectangle, as opposite sides of rectangle are equal. Step 2: Add all the given values of length and breadth Step 1: Write the given dimensions of length and breadth HOW TO CALCULATE THE PERIMETER OF RECTANGLE?īelow are the steps to find the perimeter of a rectangle The unit of the rectangle of the perimeter can be millimetres (mm), centimetres (cm), metres(m), kilometres (km), inches, feet, miles etc. So, the Perimeter formula of the rectangle = 2 x (l + b) So, Formula of perimeter of the rectangle = l + b + l + b Let ‘l’ be the lengths and ‘b’ be the breadths of the rectangle, Let us take a rectangle ABCD which has four sides i.e., AB, BC, CD and DAĪs the opposite sides of rectangle are equal, As, the opposite sides of rectangle are equal, so, the perimeter of the rectangle is equal to twice the length of the rectangle plus twice the breadth of the rectangle.ĭERIVATION OF FORMULA OF PERIMETER OF RECTANGLE The perimeter of a rectangle is the sum of all the four sides of a rectangle. The length of the diagonal of a rectangle can be calculated using the formula, d = √l 2 + b 2.The Sum of all four angles is 360 degrees.Each angle of the rectangle is 90 degrees.The diagonal of the rectangle divides it into two congruent triangles.The diagonals of a rectangle are equal.The opposite sides of the rectangle are parallel to each other.Two adjacent sides are never equal in the case of a rectangle. The opposite sides of the rectangle are equal.The longer side of the rectangle is usually referred to as a length and the smaller side is known as the breadth of a rectangle.Įxamples of rectangles are mobile phones, computer screens, rectangular carrom boards, notebooks etc All angles of a rectangle are 90 degrees or all the angles of the rectangle are right angles. Ī rectangle is a two-dimensional polygon with four sides and four angles with opposite sides that are equal and parallel to each other. For polygons, the perimeter can be defined as the total distances as you move around the shape. The length of the boundary or sides of any two-dimensional shape is called the perimeter. ![]()
