Question

A ladder is placed in such a way that its foot is at a distance of 7m from a wall and its top
reaches a window 24m above the ground. Determine the length of the ladder.​

Answer 1

The length of the ladder is 25 m

Step-by-step explanation:

Given data

• Distance of bottom end of ladder from bottom point of wall (B) = 7 m

• Distance of top end of ladder from bottom point of wall (H) = 24 m

        Let

        Length of ladder = L = Unknown

• Here we see that L, B and H form a right angle triangle. Where L will be hypotenuse of triangle.

• From formula of Pythagoras

        L² = B² + H²

        L² = 7² + 24²

        L² = 49 + 576

        L² = 625

• So

        L =25 = This is length of ladder.
