Find the perimeter of a rectangle whose length is 9 cm and breadth is ...
To find the perimeter of a rectangle, we need to add the lengths of all four sides of the rectangle.

Given:
Length of the rectangle = 9 cm

We also know that the breadth of the rectangle is equal to the side of a square of area 36 sq.cm.

Let's find the side length of the square first.

Area of a square = side * side
36 sq.cm = side * side

To find the side length, we take the square root of both sides of the equation.

√(36 sq.cm) = √(side * side)
6 cm = side

Now we know that the side length of the square is 6 cm.

Let's calculate the perimeter of the rectangle.

Perimeter of a rectangle = 2 * (length + breadth)

Substituting the given values:
Perimeter of the rectangle = 2 * (9 cm + 6 cm)
Perimeter of the rectangle = 2 * 15 cm
Perimeter of the rectangle = 30 cm

Therefore, the perimeter of the rectangle is 30 cm.

Hence, the correct answer is option B) 30 cm.
