 Hello and welcome to the session. Let us solve the following question which says, Sweetie runs round the square part of side 75 meters. Bulbul runs round a rectangular part with length 60 meters and breadth 45 meters who covers less distance. Let us now start with the solution. First let us find the distance covered by Sweetie. Now Sweetie runs round the square part of side 75 meters. So this implies distance covered by Sweetie is equal to the perimeter of the square that is the sum of its four sides. This is the distance covered by Sweetie. She runs round the square part and again runs round to this point. So perimeter is the sum of four sides that is four into side. Now each side is equal to 75 meters. So we have four into 75 meters which is equal to 300 meters. Now let us find the distance covered by Bulbul. Bulbul runs round the rectangular part of length 60 meters and breadth 45 meters. So distance covered by Bulbul is equal to the perimeter of rectangular part is equal to the sum of its length, breadth plus length and breadth. That is two times of L plus B where L is the length of the part and B is the breadth of the part. So we have two times of 60 plus 45 which is equal to 2 into 105 meters which is equal to 210 meters. Now according to the equation we have to find who covers less distance. A Sweetie covers 300 meters and Bulbul covers 200 meters since 210 meters is less than 300 meters. So this implies that Bulbul covers less distance. So our answer is Bulbul and this completes the solution. Take care and have a good day.
