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 given figure. The students are to sow seeds of flowering plans on the remaining area of the plot.
(1) Taking A as origin, find the coordinates of the vertices of the triangle.
(2) What will be the coordinates of the vertices of `Delta PQR` if C is the origin ? Also calculate the areas of the triangles in these cases. What do you observe ?

Text Solution

Verified by Experts

The correct Answer is:
(1) `(9)/(2) ` sq units
(2) `(9)/(2) ` sq units
We observe that the area of `Delta PQR` is same in both the cases.
