The side of the square is 6dm, and the sides of the rectangle are 4cm and 9cm. Compare the areas of these shapes.

the area of a square is the product of its two sides, that is, 6dm = 60cm (we translate dm into cm, because the sides of the rectangle are given to us in cm)
square area = 60 × 60 = 360cm
the area of a rectangle is also the product of its two sides
4 × 9 = 36cm
based on the above calculations, we can conclude that the area of the square is 10 times the area of the rectangle.
