Answer:

169

Step-by-step explanation:

let x be ladder length

to find x use hypotenuse theorem

x^2 = 5^2 + 12^2

x^2 = 25 + 144

x^2 = 169

x = sq. root of 169

x = 13

Correct Question :

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

Answer :

  • The length of the ladder = 13 m.

Given :

  • The distance between foot of a ladder and a wall = 5 cm.
  • Height of the window to ground = 12 cm.

To Find :

  • The length of the ladder.

Solution :

Let,

The length of the ladder be x.

By pythagoras theorem,

 \large \underline{ \boxed{ \orange{ \sf{ {a}^{2} =  {b}^{2} +  {c}^{2}   }}}}

Where,

  • a = hypotenuse.
  • b = base.
  • c = perpendicular.

Given,

  • Base = b = 5 cm.
  • Perpendicular = c = 12 cm.

 :  \implies \rm  {x}^{2}  =  {(5 \: m)}^{2}  +  {(12 \: m)}^{2}  \\  \\  :  \implies \rm  {x}^{2}  = 25 \:  {m}^{2}  +  {144 \: m}^{2}  \\  \\ :  \implies \rm  {x}^{2}  = 169 \:  {m}^{2}  \\  \\ :  \implies \rm x =  \sqrt{169 \:  {m}^{2} }  \\ \\ :  \implies \rm x = 13 \: m

Hence,

The length of the ladder is 13 m.
