Question

дом имеет прямоугольную форму.Длина дома 12 м,а ширина на 2м50см меньше.Треть площади занимают хозяйственные помещения,а остальное-жилые комнаты.Во сколько раз больше площадь жилых помещений?

Answer 1

12 м=1200 см

2 м 50 см=250 см

1) 1200-250=950 (см) - ширина дома

2) 1200*950=1140000 (кв.см) - площадь дома

1140000 кв.см=114 кв.м

3) 114:3=38 (кв.м) - хозяйственные помещения

4) 114-38=76 (кв.м) - жилые комнаты

5) 76:38=2 (р.)

Ответ: площадь жилых помещений больше в 2 раза.

Answer 2

Calculation of the Area of the House

To find the area of the house, we need to calculate the length and width of the house based on the given information.

Given: - Length of the house = 12 m - Width of the house = 2 m 50 cm less than the length

To calculate the width of the house, we subtract 2 m 50 cm from the length:

Width of the house = Length of the house - 2 m 50 cm

Let's convert 2 m 50 cm to meters for easier calculation:

2 m 50 cm = 2.5 m

Now we can calculate the width of the house:

Width of the house = 12 m - 2.5 m = 9.5 m

Calculation of the Area of the House

To calculate the area of the house, we multiply the length and width:

Area of the house = Length of the house * Width of the house

Area of the house = 12 m * 9.5 m

Area of the house = 114 square meters

Calculation of the Area of the Living Rooms

Given: - One-third of the area is occupied by utility rooms - The rest is occupied by living rooms

To calculate the area of the living rooms, we need to find two-thirds of the total area:

Area of the living rooms = Two-thirds of the area of the house

Area of the living rooms = (2/3) * Area of the house

Area of the living rooms = (2/3) * 114 square meters

Area of the living rooms = 76 square meters

Calculation of the Ratio of the Area of the Living Rooms to the Area of the Utility Rooms

To find the ratio of the area of the living rooms to the area of the utility rooms, we divide the area of the living rooms by the area of the utility rooms:

Ratio = Area of the living rooms / Area of the utility rooms

Ratio = 76 square meters / 38 square meters

Ratio = 2

Conclusion

The area of the living rooms is twice the area of the utility rooms.
