Question

Посадки леса занимают 420 га. ели занимают 55% этой площади, а сосны 25%. на сколько гектаров площадь, занята елями, больше площади, занятой соснами? помогите решить плизз)))

Answer 1

420 *55/100 = 231 га - ели

420*25/100 = 105 га  - сосны

231 - 105 = 126 га площадь занятая елями больше площади занятой соснами

Answer 2

Calculation of the Area Occupied by Elms and Pines

To solve this problem, we need to calculate the difference in area between the elms and the pines.

Given: - Total forest area: 420 hectares - Elms occupy 55% of the total area - Pines occupy 25% of the total area

To find the area occupied by elms, we can multiply the total area by the percentage occupied by elms: Area occupied by elms = 420 hectares * 55%

To find the area occupied by pines, we can multiply the total area by the percentage occupied by pines: Area occupied by pines = 420 hectares * 25%

To calculate the difference in area between elms and pines, we subtract the area occupied by pines from the area occupied by elms: Difference in area = Area occupied by elms - Area occupied by pines

Let's calculate the values step by step:

1. Calculate the area occupied by elms: Area occupied by elms = 420 hectares * 55%

2. Calculate the area occupied by pines: Area occupied by pines = 420 hectares * 25%

3. Calculate the difference in area: Difference in area = Area occupied by elms - Area occupied by pines

Let's perform the calculations:

1. Calculate the area occupied by elms: Area occupied by elms = 420 hectares * 55% = 231 hectares 2. Calculate the area occupied by pines: Area occupied by pines = 420 hectares * 25% = 105 hectares 3. Calculate the difference in area: Difference in area = Area occupied by elms - Area occupied by pines = 231 hectares - 105 hectares = 126 hectares

Therefore, the area occupied by elms is 126 hectares more than the area occupied by pines.

Please note that the provided sources did not contain specific information about the calculation of the area occupied by elms and pines. However, the calculations performed above are based on the given percentages and the total forest area.
