## Case Study Questions Class 9 Maths Chapter 9

Case Study 1. A group of students is learning about the areas of parallelograms and triangles. They came across the following scenario:

Rahul and Sana participated in a gardening project where they needed to create rectangular plots in their backyard. They made the following observations:

1. Rahul’s rectangular plot has a length of 10 meters and a height of 5 meters.
2. Sana’s rectangular plot has a length of 12 meters and a height of 6 meters.
3. Both plots have the same base and height.

Based on this information, the students were asked to analyze the areas of the parallelograms formed by the rectangular plots. Let’s see if you can answer the questions correctly:
