Question

Поле площадью 12 га отвели под строительство конно-спортивного комплекса. Ипподром занимает 3/4 этой площади, а остальную часть – конюшни и другие служебные постройки, причем площадь конюшен в два раза больше площади других служебных построек. Сколько аров занимают конюшни?

Answer 1

Ипподром=12/4*3=9 га
12-9=3 га занимают конюшни и постройки
2 га занимают конюшни, 1 га занимают постройки

Answer 2

Calculation of the Area Occupied by Stables

To calculate the area occupied by the stables, we need to determine the total area of the complex and the proportion of that area occupied by the stables.

Given: - The total area of the field is 12 hectares. - The racetrack occupies 3/4 of the total area. - The stables and other service buildings occupy the remaining 1/4 of the total area. - The area of the stables is twice the area of the other service buildings.

Let's calculate the area occupied by the stables step by step:

1. Calculate the area of the racetrack: - The racetrack occupies 3/4 of the total area. - 3/4 of 12 hectares is (3/4) * 12 = 9 hectares.

2. Calculate the area of the other service buildings: - The other service buildings occupy 1/4 of the total area. - Since the area of the stables is twice the area of the other service buildings, the area of the other service buildings is 1/3 of the remaining 1/4. - (1/3) * (1/4) * 12 hectares = 1 hectare.

3. Calculate the area of the stables: - The area of the stables is twice the area of the other service buildings. - 2 * 1 hectare = 2 hectares.

Therefore, the stables occupy 2 hectares of the total area.

Answer: The stables occupy 2 hectares.
