1. Area of Square is greater than Area of Rectangle by 400 cm²

   We Have :-
   

   A Square of side 60 cm and a Rectangle of length 80 cm have the same perimeter

   To Find :-
   

   Which encloses more Area

   Formula Used :-
   

   Perimeter of Square = 4 * side

   Area of Square = side * side

   Perimeter of Rectangle = 2 ( Length + Breadth )

   Area of Rectangle = Length * Breadth

   Solution :-
   

   According to Question

   Perimeter of Square = Perimeter of Rectangle

   4 * ( 60 ) = 2 ( 80 + b )

   240 = 160 + 2b

   2b = 80

   b = 40 cm

   Area of Rectangle = Length * Breadth

   = 80 * 40

   = 3200 cm²

   Area of Square = side * side

   = 60 * 60

   = 3600 cm²

   Area of Square is greater than Area of Rectangle by 400 cm²
