VALUE BASED QUESTIONS

Q1. A group of students plan to put-up a banner in favour of respect towards girls and women, against a wall. They placed a ladder against the wall such that its foot is at a distances of 2.5 m from the wall and its top reaches a window 6 m above the ground.

(i) Find the length of the ladder.
(ii) Which mathematical concept is used in this problem?
(iii) By putting up a banner in favour of respect to women, which value is depicted by the group of students? Sol. (i) Let AB be the ladder and CA be the wall with the window at A. Also,
BC = 2.5 m
CA = 6m
∴ In rt ΔACB, we have
AB2 = BC2 + CA2 [Using Pythagoras Theorem]
= (2.5)2 + (6)2
= 6.25 + 36 = 42.25

⇒ Thus, the length of the ladder is 6.5 m.
(ii) Triangles (Pythagoras Theorem)
(iii) Creating positive awareness in public towards regards to women.
