The rectangle is 3 cm wide and 6 cm long. It is divided into squares with a side of 1 cm.

The rectangle is 3 cm wide and 6 cm long. It is divided into squares with a side of 1 cm. How many squares are there? What is the area of this rectangle in square centimeters?

First of all, let us find the area of a given rectangle if the lengths of its two sides are known by the problem statement. To do this, calculate the product of its length and width:

S = 6 * 3 = 18 (cm²).

Now we will determine the area of each square into which this rectangle is divided, for which we will square the length of its side:

S = 1² = 1 (cm²).

Thus, to find how many squares the rectangle is divided into, divide the area of the rectangle by the found area of each of the squares:

18: 1 = 18 (squares).

Answer: it turned out 18 squares.
