According to the terms of the assignment, it is necessary to determine the area of the entire apartment if we know that its 25% is S of one room, equal to 12 m².
To solve, you need to make a proportion:
x = 100%.
12 m² = 25%.
Let’s write the equation, acting according to the “cross” rule and find the value of the variable:
x = 100 * 12: 25 = 1200: 25 = 48 m².
Problem type: direct proportional relationship.
