The correct option is A equal to
Area of square = side × side
Hence, area of square of side 6 cm = 6 cm×6 cm= 36 cm2.
Area of rectangle = length × breadth
Hence, area of rectangle of length 9 cm and breadth 4 cm = 9 cm×4 cm = 36 cm2.
Therefore, area of a square of side 6 cm is equal to the area of a rectangle of length 9 cm and breadth 4 cm.
