Question

квартира состоит из трех комнат. первая комната на 5 м2 меньше второй, а вторая на 8 м2 меньше третьей. найдите общую площадь трех комнат, если площадь самой маленькой из них равна 10 м2.

Answer 1

по условию задачи видно,что самая маленькая комната-первая,значит её площадь 10 кв м,поэтому

1)10+5=15 кв м площадь второй комнаты

2)15+8=23 кв м площадь третьей комнаты

3)10+15+23=48 кв м площадь всех комнат

Calculation of the Total Area of Three Rooms

To find the total area of 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 smaller than the first room, so its area is x - 5 square meters. Similarly, the third room is 8 square meters smaller than the second room, so its area is (x - 5) - 8 square meters.

We are also given that the area of the smallest room is 10 square meters. Therefore, we can set up the following equation:

x - 5 - 8 = 10

Simplifying the equation, we get:

x - 13 = 10

Adding 13 to both sides of the equation, we find:

x = 23

Now that we know the area of the first room (x = 23 square meters), we can calculate the areas of the second and third rooms:

- The area of the second room is x - 5 = 23 - 5 = 18 square meters. - The area of the third room is (x - 5) - 8 = 18 - 8 = 10 square meters.

Therefore, the total area of the three rooms is:

23 + 18 + 10 = 51 square meters.

So, the total area of the three rooms is 51 square meters.
