Calculating the Area Plowed by the Brigade

To calculate the area plowed by the brigade over three days, we can use the information provided in the question. Let's break it down step by step.

1. Plowing on the First Day: - Let's assume the area plowed on the first day is represented by x hectares.

2. Plowing on the Second Day: - Given that the brigade plowed three times less on the second day than on the first day, the area plowed on the second day is 1/3 * x hectares.

3. Plowing on the Third Day: - The brigade plowed five times more on the third day than on the second day, and it plowed 28 hectares more than on the first day. This gives us the equation: 5 * (1/3 * x) = x + 28.

Let's solve for x to find the area plowed on the first day.

Solving for x

Using the equation 5 * (1/3 * x) = x + 28: - 5/3 * x = x + 28 - 5x = 3x + 84 - 2x = 84 - x = 42

So, the area plowed on the first day (x) is 42 hectares.

Total Area Plowed Over Three Days

Now that we know the area plowed on the first day, we can calculate the total area plowed over three days.

- First day: 42 hectares - Second day: 1/3 * 42 hectares = 14 hectares - Third day: 5 * 14 hectares = 70 hectares

Therefore, the brigade plowed a total of 42 + 14 + 70 = 126 hectares over three days.

So, the brigade plowed a total of 126 hectares over three days.
