Question

Квартира состоит из трёх комнат.первая комната на 5м в квад.меньше второй,а вторая на 8м в квад.меньше третьей.найдите общую площадь трех комнат,если площадь самой маленькой из них равна 10м виквад.

Answer 1

по условию задачи получается.что самая маленькая комната-первая и её площадь 10 кв м,значит

10+5=15 кв м площадь второй комнаты

15+8=23 кв м площадь третьей комнаты

10+15+23=48 кв м площадь всей квартиры

Answer 2

Calculation of the Total Area of Three Rooms

To find the total area of the three rooms, we need to determine the sizes of the second and third rooms. We are given that the first room is 5 square meters smaller than the second room, and the second room is 8 square meters smaller than the third room. Additionally, we know that the smallest room has an area of 10 square meters.

Let's calculate the areas of the second and third rooms:

1. Let's assume the area of the second room is x square meters. 2. Since the first room is 5 square meters smaller than the second room, the area of the first room is x - 5 square meters. 3. Similarly, since the second room is 8 square meters smaller than the third room, the area of the third room is x + 8 square meters.

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

Total area = Area of the first room + Area of the second room + Area of the third room

Total area = (x - 5) + x + (x + 8) square meters

Simplifying the equation:

Total area = 3x + 3 square meters

We are given that the smallest room has an area of 10 square meters. Substituting this value into the equation:

10 = 3x + 3

Solving for x:

3x = 10 - 3

3x = 7

x = 7/3

Therefore, the area of the second room (x) is approximately 2.33 square meters.

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

Total area = 3x + 3

Total area = 3(2.33) + 3

Total area = 6.99 + 3

Total area ≈ 9.99 square meters

Therefore, the total area of the three rooms is approximately 9.99 square meters.

Please note that the calculations are approximate due to rounding.
