Question

Площадь одной комнаты составляет 2/7 всей площади квартиры.Чему равна площадь этой комнаты , если она на 25 кв. м меньше ,чем площадь всей квартиры. Помогите плиииз

Answer 1

Пусть x кв. м - площадь квартиры, тогда (2/7)х - площадь комнаты. По условию задачи составим уравнение:

х-(2/7)х=25;  (5/7)х=25;  х=25: 5/7;  х=25*7/5=35кв.м - площадь квартиры;

площадь комнаты - 35-25=10(кв.м)

ответ:10 кв. м

Answer 2

Calculation of the Room's Area

To find the area of the room, we need to determine the total area of the apartment and then calculate 2/7 of that area. We are given that the room is 25 square meters smaller than the total area of the apartment.

Let's denote the total area of the apartment as A and the area of the room as R.

According to the given information, the area of the room is 2/7 of the total area of the apartment minus 25 square meters:

R = (2/7)A - 25

To find the value of R, we need to know the total area of the apartment (A). Unfortunately, the total area of the apartment is not provided in the question. Therefore, we cannot calculate the exact area of the room without this information.

If you have the total area of the apartment, please provide it so that we can calculate the area of the room accurately.
