Rectangular garden of Seema = length 22m ; breadth 15m
Square garden of Rama = Side 21m
We need to find its perimeter,
Perimeter of rectangle = 2 ( l + b )
= 2 ( 22 + 15 )
= 2 x 37
= 74
Perimeter of square = 4a
= 4 x 21
= 84
We need to compare the following perimeter,
Perimeter of square is bigger than rectangle.
So, Rama garden is bigger.
Now we need to find by how much?
So we will subtract perimeter of Rama and Seema
84-74=10
