Problem Analysis

To solve this problem, we need to determine the total area of the farm based on the given information. We know that 3/5 of the farm is allocated for cotton and 3/4 of the remaining area is used for grains. We are also given that 1080 hectares of land are sown with grains.

Solution

Let's break down the problem step by step:

1. Calculate the area allocated for cotton: - We are told that 3/5 of the entire farm is used for cotton. - To find this area, we can multiply the total area of the farm by 3/5. - Let's represent the total area of the farm as x hectares. - The area allocated for cotton is then (3/5) * x hectares.

2. Calculate the remaining area for grains: - We know that 3/4 of the remaining area is used for grains. - To find this area, we can subtract the area allocated for cotton from the total area of the farm. - The remaining area for grains is then (1 - 3/5) * x hectares.

3. Calculate the area sown with grains: - We are given that 1080 hectares of land are sown with grains. - We can set up the following equation to find the total area of the farm: (1 - 3/5) * x = 1080

Let's solve this equation to find the total area of the farm:

(1 - 3/5) * x = 1080

Simplifying the equation:

(2/5) * x = 1080

Multiplying both sides by 5/2 to isolate x:

x = 1080 * (5/2)

Calculating the value of x:

x = 2700

Therefore, the total area of the farm is 2700 hectares.

Answer

The farm has a total area of 2700 hectares.
