Answer» We will discuss here how to find the perimeter of a rectangle. We know perimeter of a rectangle is the total length (DISTANCE) of the boundary of a rectangle.ABCD is a rectangle. We know that the opposite sides of a rectangle are equal.AB = CD = 5 cm and BC = AD = 3 cmSo, the perimeter of the rectangle ABCD = AB + BC + CD + AD = 5 cm + 3 cm + 5 cm + 3 cm = 16 cmPerimeter of a RectangleIt can be written as 5 cm + 5 cm + 3 cm + 3 cm = (2 × 5) cm + (2 × 3) cm = 2 (5 + 3) cm = 2 × 8 cm = 16 cmWe add length and breadth twice to find the perimeter of a rectangle.Perimeter of a rectangle = 2 (length + breadth) |
