Question
Jagdish has a field which is in the shape of a right angled triangle AQC. He wants to leave a space in the form of a square PQRS inside the field for growing wheat and the remaining for growing vegetables (as shown in the figure). In the field, there is a pole marked as O.

Based on the above information, answer the following questions:
(i) Taking O as origin, coordinates of P are (−200,0) and of Q are (200,0). PQRS being a square, what are the coordinates of R and S? Solution
1
Side PQ=200−(−200)=400 m. Since PQRS is a square with PQ along x-axis, R and S are directly above Q and P respectively at height 400.
