Perimeter of squareLet’s take a square We know that In a square, all sides are equal In a rectangle, opposite sides are equal So, all sides have length a Now, Perimeter of square = Sum of all sides = a + a + a + a = 4a Thus, Perimeter of square = 4a = 4 × Side of square Let’s do some examples Find perimeter of a square whose side is 15 cm Given, Side of square = a = 15 cm So, Perimeter of square = 4 × side of square = 4a = 4 × 15 = 60 cm Thus, Perimeter of square is 60 cm Find perimeter of a square whose side is 0.5 m Given, Side of square = a = 0.5 m = 0.5 × 100 cm = 50 cm So, Perimeter of square = 4 × Side of square = 4a = 4 × 50 = 200 cm = 200/100 m = 2 m
