Final answer:
To find the result for the farmer who wants to fence off a four-sided plot of flat land, we need to subtract the sum of the lengths of the three sides from 360 meters.
Step-by-step explanation:
To find the result for the farmer who wants to fence off a four-sided plot of flat land, we need to use the fact that the sum of the lengths of all four sides of a rectangle is equal to the perimeter of the rectangle.
In this case, the farmer has 360 meters of fencing, which will be used for three sides of the garden.
So, the sum of the lengths of the three sides will be 360 meters.
Let's call the length of one of the sides x.
Since the fourth side does not need fencing, its length is equal to the length of the side of the house.
Therefore, the result for the farmer can be found by subtracting the sum of the lengths of the three sides from 360 meters.
So, the result is 360 - 3x.
