CASE STUDY QUESTION 1-Class X-Maths

**The Class X students of a secondary school in Krishinagar have been allotted a rectangular plot of land for their gardening activity. Sapling of Gulmohar are planted on the boundary at a distance of 1 m from each other. There is a triangular grassy lawn in the plot as shown in the below figure. The students are to sow seeds of flowering plants on the remaining area of the plot.**

(i) P (4, 6), Q(3, 2), R(6, 5)

(ii) P (3, 2), Q(4, 6), R(6, 5)

(iii) P (4, 6), Q3, 2), R(5, 6)

(iv) P (4, 6), Q(2, 3), R(6,5)

**(b) What is the midpoint of side PQ, when A is the origin?**

(i) (7/2, 9/2)

(ii) (7/2, 4)

(iii) (23/2, 9/2)

(iv) none of these

**(c) What will be the coordinates of the vertices of a ∆PQR if C is the origin?**
