Mathematics — CBSE Class 10 board question

Q1. [4]
Observe the map of Jaipur city placed on a Cartesian plane. Taking Rambagh Palace as origin, the location of some places are given below: Point A: (−4, 2) — Rajasthan High Court Point B: (4, −4) — Birla Mandir Point C: (4, 3) — Heera Bagh Point D: (−5, −2) — Amar Jawan Jyoti
Based on the above, answer the following questions:
  1. (i) Advocate Rehana stays at Heera Bagh. How much distance she has to cover daily to go to the court and coming back home? [1]
  2. (ii) There is a crossing on X-axis which divides AD in a certain ratio. Find the ratio. [1]
  3. (iii) Is Birla Mandir equidistant from Heera Bagh and Amar Jawan Jyoti? Justify your answer. [2]

Model Answer

(i) Distance from Heera Bagh C(4, 3) to High Court A(−4, 2):

$$AC = \sqrt{(4-(-4))^2 + (3-2)^2} = \sqrt{64+1} = \sqrt{65} \text{ units}$$

Daily distance (to court and back) = $2\sqrt{65}$ units

(ii) Let the point on X-axis dividing AD in ratio k : 1 be (x, 0).

A = (−4, 2), D = (−5, −2)

Using section formula for y-coordinate:

$$0 = \frac{k(-2) + 1(2)}{k+1} \Rightarrow -2k + 2 = 0 \Rightarrow k = 1$$

∴ AD is divided in ratio 1 : 1

(iii) B = (4, −4), C = (4, 3), D = (−5, −2)

$$BC = \sqrt{(4-4)^2+(-4-3)^2} = \sqrt{0+49} = 7 \text{ units}$$

$$BD = \sqrt{(4-(-5))^2+(-4-(-2))^2} = \sqrt{81+4} = \sqrt{85} \text{ units}$$

Since BC ≠ BD, Birla Mandir is NOT equidistant from Heera Bagh and Amar Jawan Jyoti.
