उत्तर
Given, Length of rectangular playground, AB = x
And breadth of rectangular playground, BC = y
∵ FCDE is a square, ie. FC = CD = EF = DE = x ...[∵ All sides of a square are equal]
∵ ABCF is a rectangle, i.e. AB = FC = x and BC = AF = y
Now, perimeter of combined (playground + lawn) = Sum of all sides
= AB + BC + CD + DE + EF + FA
= x + y + x + x + x + y
= 4x + 2y
