Question

Участок земли площадью 180а радспределен под застройку,сад и огород.Под застройку отведено две девятых участка,а из оставшейся части тренадцать двадцать восьмых занимает огород.Какова площадь сада?

Answer 1

Вся площадь - 180
2/9 * 180 = 40а - застройка
180- 40 = 140а -оставшаяся часть
140* 13/28 =  65а  -огород
180-40-65 = 75а площадь сада

Answer 2

Calculation of Garden Area

To calculate the area of the garden, we need to subtract the area allocated for construction from the total area of the land. According to the given information:

- The total area of the land is 180a. - Two-ninths of the land is allocated for construction. - Thirteen-twenty-eighths of the remaining land is occupied by the garden.

Let's calculate the area of the garden step by step:

1. Calculate the area allocated for construction: - Two-ninths of the land is allocated for construction. - So, the area allocated for construction is (2/9) * 180a.

2. Calculate the remaining land area: - Subtract the area allocated for construction from the total area of the land: - Remaining land area = Total land area - Area allocated for construction - Remaining land area = 180a - (2/9) * 180a

3. Calculate the area occupied by the garden: - Thirteen-twenty-eighths of the remaining land is occupied by the garden. - So, the area occupied by the garden is (13/28) * (180a - (2/9) * 180a).

4. Simplify the expression for the area of the garden: - Multiply and simplify the fractions to get the final expression for the garden area.

Let's calculate the area of the garden using the given information:

Area allocated for construction = (2/9) * 180a Remaining land area = 180a - (2/9) * 180a Area occupied by the garden = (13/28) * (180a - (2/9) * 180a)
