Question

Поле площадью 12 га отвели под строительство конно-спортивного комплекса. Ипподром занимает 3/4 этой площади, а остальную часть - конюшни и другие служеб. постройки, причём площадь конюшен в два раза больше площади других служ. построек. Сколько аров занимают конюшни? (решать не уравнением).

Answer 1

1)12/4=3 га занимают конюшни и другие служеб.постройки

2)3/3=1 га служебные постройки

3)3-1=2 га конюшни

 

1га=100 арам

значит: 2*100=200 аров конюшни

Answer 2

Calculation of the Area Occupied by Stables

To calculate the area occupied by the stables, we need to first determine the total area of the horse racing track and the remaining area for stables and other service buildings.

Given: - Total area: 12 hectares - Horse racing track occupies 3/4 of the total area - Stables and other service buildings occupy the remaining area, with the stables being twice the size of the other service buildings

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

1. Calculate the area occupied by the horse racing track: - The horse racing track occupies 3/4 of the total area. - Area of the horse racing track = (3/4) * (12 hectares) = 9 hectares.

2. Calculate the area occupied by the other service buildings: - The remaining area is allocated to the stables and other service buildings. - The stables occupy twice the area of the other service buildings. - Let's assume the area occupied by the other service buildings is x hectares. - The stables occupy 2x hectares. - The sum of the areas of the other service buildings and the stables is equal to the remaining area, which is 12 hectares - 9 hectares = 3 hectares. - x + 2x = 3 hectares - 3x = 3 hectares - x = 1 hectare

3. Calculate the area occupied by the stables: - The stables occupy twice the area of the other service buildings. - Area occupied by the stables = 2 * (1 hectare) = 2 hectares.

Therefore, the stables occupy 2 hectares of the total area allocated for the construction of the equestrian sports complex.
