Answer 2

Calculating the Area Occupied by Snow Guards

To calculate the area occupied by snow guards on the field, we can use the given information that 2/3 of the field is covered by snow ridges and the rest is covered by snow guards.

Given: - Total area of the field: 420 hectares - Snow ridges cover 2/3 of the field

Let's calculate the area occupied by snow guards.

Calculation

First, we need to find the area covered by snow ridges: \[ \text{Area of snow ridges} = \frac{2}{3} \times \text{Total area of the field} \]

\[ \text{Area of snow ridges} = \frac{2}{3} \times 420 \]

\[ \text{Area of snow ridges} = 280 \]

Now, we can find the area occupied by snow guards: \[ \text{Area of snow guards} = \text{Total area of the field} - \text{Area of snow ridges} \]

\[ \text{Area of snow guards} = 420 - 280 \]

Area of snow guards = 140 hectares

Therefore, the snow guards occupy an area of 140 hectares on the field.
