Perimeter of rectangleLet’s take a rectangle We know that In a rectangle, opposite sides are equal So, two sides have length l, and two sides have breadth b Now, Perimeter of rectangle = Sum of all sides = l + b + l + b = 2l + 2b = 2 (l + b) Thus, Perimeter of rectangle = 2 (l + b) Let’s do some examples Find perimeter of rectangle where length is 15cm & breadth is 9 cm Given, Length = l = 15 cm Breadth = b = 9 cm Perimeter of rectangle = 2 × (Length + Breadth) = 2 × (15 + 9) = 2 × 24 = 48 cm So, perimeter of rectangle is 48 cm Find perimeter of rectangle where length & breadth are 0.5 m & 0.2 m respectively. Given, Length = l = 0.5 cm Breadth = b = 0.2 cm Perimeter of rectangle = 2 × (Length + Breadth) = 2 × (0.5 + 0.2) = (2 × 0.7) = 1.4 m = 1.4 × 100 cm = 140 cm
