Find the coordinate of a point P which divides the line segment joining :
A (3, -3) and B (6, 9) in the ratio 1 :2.
उत्तर
Let the point P divides the line segment AB in the ratio 1: 2.
∴ coordinates of Pare
x = `(1 xx 6 + 2 xx 3)/(1 + 2) = 4`
y = `(1 xx 9 + 2"x" - 3)/(1 + 2) = 1`

Read the following passage:
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 :
- 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?
- (a) What is the area of square PQRS?
