Question

Посадки леса занимают 420 га, Ели занимают 63.5% этой площади а сосны 29% На сколько гектаров площади занятя елями больше площади занято соснами

Answer 1

1) 420/100*63.5 = 266.7 га занимают ели
2) 420/100*29=121.8 га занимают сосны
3) 266.7-121.8=144.9 га больше занимают ели
ответ: на 144.9 га

Answer 2

Calculation of Forest Areas

To calculate the difference in area occupied by spruce and pine trees, we first need to determine the actual areas occupied by each tree type.

Given the following information: - Total forest area: 420 hectares - Spruce occupies 63.5% of the total area - Pine occupies 29% of the total area

We can calculate the areas as follows:

1. Area occupied by spruce: - Spruce occupies 63.5% of the total area - Area occupied by spruce = 63.5% of 420 hectares - Area occupied by spruce = 0.635 * 420 hectares

2. Area occupied by pine: - Pine occupies 29% of the total area - Area occupied by pine = 29% of 420 hectares - Area occupied by pine = 0.29 * 420 hectares

Calculation

Let's calculate the difference in area between spruce and pine:

1. Area occupied by spruce: 0.635 * 420 hectares = 266.7 hectares 2. Area occupied by pine: 0.29 * 420 hectares = 121.8 hectares

To find the difference in area between spruce and pine, we subtract the area occupied by pine from the area occupied by spruce:

Difference in area = Area occupied by spruce - Area occupied by pine

Difference in area = 266.7 hectares - 121.8 hectares

Therefore, the area occupied by spruce is greater than the area occupied by pine by approximately 144.9 hectares.

Please note that the calculations are based on the given percentages and the total forest area of 420 hectares.
