A farmer had a plot in the shape of a parallelogram. He divided into three equal parts, each of which was a separate parallelogram. He then gave his son one-third of the land. The son, who realized that the district in which he lived had no school, decided to set one school up in his plot, given to him by his father.

(i) Show how the proposal of the farmer can be implemented, with the help of a diagram. How much part of the land does the son get? Justify the proposal.
(ii) Was the son 's decision right?

(i) To implement the farmer's proposal, we can start by drawing a parallelogram to represent the original plot of land. Then, divide the parallelogram into three equal parts by drawing two parallel lines through it. This will create three separate parallelograms. Now, assign one of these parallelograms to the son as his portion of the land.

To find out how much land the son gets, we need to understand that the original plot was divided into three equal parts. So, each of the three parallelograms has the same area. Since the son receives one of these parallelograms, he gets one-third (1/3) of the original land.

Here is a diagram representing the division of land:

```

(ii) Whether the son's decision was right or not depends on context and various factors. We can't determine the correctness of the decision solely based on the information provided. Some considerations for evaluating the son's decision could include the availability of resources, the feasibility of setting up a school on that plot, the location of the plot in relation to the community's needs, and any potential legal or logistical challenges.
