Answer 2

Calculation of the Total Area of the Three Rooms

To find the total area of the three rooms, we need to determine the area of each room and then add them together.

Let's denote the area of the first room as x square meters. According to the given information, the second room is 5 square meters larger than the first room, so its area is x + 5 square meters. Similarly, the third room is 8 square meters larger than the second room, so its area is (x + 5) + 8 square meters.

Given that the smallest room has an area of 10 square meters, we can set up the following equation:

x = 10

Substituting this value into the expressions for the areas of the second and third rooms, we have:

Second room area: (10 + 5) = 15 square meters Third room area: (15 + 8) = 23 square meters

Now, we can calculate the total area by adding the areas of the three rooms:

Total area = First room area + Second room area + Third room area Total area = 10 + 15 + 23 = 48 square meters

Therefore, the total area of the three rooms is 48 square meters.
