Answer 2

Calculation of the Area of the Battlefield

To find the area of the battlefield, we need to multiply the length of one side by the length of the other side. Given that one side is 120 meters long and the other side is 50 meters long, the area of the battlefield can be calculated as follows:

Area = Length * Width Area = 120m * 50m Area = 6000m²

Therefore, the total area of the battlefield is 6000 square meters.

Calculation of the Enemy-Occupied Area

According to the information provided, the enemies occupy one-fourth (1/4) of the battlefield. To find the area occupied by the enemies, we can calculate one-fourth of the total area of the battlefield:

Enemy-Occupied Area = (1/4) * Total Area Enemy-Occupied Area = (1/4) * 6000m² Enemy-Occupied Area = 1500m²

Therefore, the enemies occupy an area of 1500 square meters on the battlefield.

Calculation of the Area Occupied by the Niche

The niche occupies an area of 1300 square meters on the battlefield. This area is separate from the enemy-occupied area. Therefore, to find the area occupied by the niche, we subtract the niche area from the enemy-occupied area:

Area Occupied by the Niche = Enemy-Occupied Area - Niche Area Area Occupied by the Niche = 1500m² - 1300m² Area Occupied by the Niche = 200m²

Therefore, the niche occupies an area of 200 square meters on the battlefield.

Calculation of the Remaining Area for Grazing Goats

To find the remaining area of the battlefield where the goats graze, we subtract the sum of the enemy-occupied area and the niche area from the total area of the battlefield:

Remaining Area = Total Area - (Enemy-Occupied Area + Niche Area) Remaining Area = 6000m² - (1500m² + 200m²) Remaining Area = 4300m²

Therefore, the remaining area of the battlefield where the goats graze is 4300 square meters.

Calculation of the Number of Goats Grazing

According to the information provided, there are 3 goats grazing per 5 square meters. To find the number of goats grazing on the remaining area of the battlefield, we can calculate the ratio of the remaining area to the area per 3 goats:

Number of Goats Grazing = (Remaining Area / Area per 3 Goats) Number of Goats Grazing = (4300m² / 5m²) * 3 Number of Goats Grazing = 2580 goats

Therefore, there are 2580 goats grazing on the remaining area of the battlefield.

In summary, there are 2580 goats grazing on the field of battle.
