In a rectangle with sides 18 cm and 6 cm long, this rectangle was divided into 4 equal parts. What is the area of one part?

1.) First, we write down the formula by which we find out the area of the rectangle.
S = ab, where a is one side of the rectangle and b is the other side.
Now let’s calculate the area of this rectangle.
In the problem, a = 18 cm and b = 6 cm.
Substitute these values into the area formula.
S = 18 × 6.
S = 108 (cm²).
2.) According to the problem statement, this rectangle was divided into 4 equal parts.
Find the area of one specified part.
To do this, divide the total area of the rectangle by 4.
S = 108: 4.
S = 27 (cm²).
Answer: 27 cm² is the area of one part.
