Correct question:

A ladder is placed in such a way that its foot is at a distance of 5 metre from a wall and its top reaches at window 12 metre above the ground determine the length of the ladder.

Given:

Distance between foot of ladder and wall = \tt{5m}

Height of the window from to ground = \tt{12m}

Length of the ladder = x

All the things together form a right angled triangle, as given in image.

∴We will solve by using Pythagoras theoram.

Solution:

\tt{x^2} = \tt{5^2}+\tt{12^2}

\tt{x^2} = \tt\sqrt{144+25}

\tt{x^2} = \tt\sqrt{169}

\tt{x} = \tt{13}

Length of the ladder is 13m.

Solution :-

Base = 9 metre

Height = 12 metre

Hypotenuse = ?

By using the formula,

= +

x² = (9)² + (12)²

x² = 81 + 144

x² = 225

x = √225

x = 15 m

Therefore, the length of the ladder is 15 metre.

Hope it helps!
