उत्तर
a. Lions are at a distance of A units from road Y and f units from road X.
∴ The location of lions is represented by the point (Af)
b. Observing the map carefully, we see that (D, f) denotes the location of monkeys and (C, d) denotes the location of elephants.
c. Toilets are located on the road Y at a distance of e units from the origin. Hence, the location of toilets is (0, e).
d. Canteen is located at a distance of C units from road Y and c units from road X. Hence, the location of the canteen is (C, c).
