Distance = 26 m

Step-by-step explanation:

Given:

  • A man goes 10 m due east.
  • Then he goes 24 m due west.

To Find:

  • Distance of man from the starting point.

Solution: Let the man started from point O.

  • He went 10 m in east i.e O to M.
  • Then he went 24 m in north i.e M to G.

Now in right angled triangle OMG.

  • OM = Base (10 m)
  • MG = Perpendicular (24 m)
  • OG = Hypotenuse

Using Pythagoras theorem in this ∆.

= Perpendicular² + Base²

\implies{\rm } OG² = MG² + OM²

\implies{\rm } OG² = 24² + 10²

\implies{\rm } OG² = 576 + 100

\implies{\rm } OG² = 676

\implies{\rm } OG = 676

\implies{\rm } OG = 26

Hence, his distance from the starting point is 26 m.

Let the Man Start Journey from the Middle Point A, he goes 10 metres due east to Point B and then 24 metres due North to Point C.

He Started Journey from Point A & Now he is at Point C, this forms a Right Angle Triangle.

\underline{\bigstar\:\textsf{By Pythagoras Theorem :}}

:\implies\sf (Hypotenuse)^2 = (Perpendicular)^2+(Base)^2\\\\\\:\implies\sf (AC)^2=(BC)^2+(AB)^2\\\\\\:\implies\sf (AC)^2=(24 \:m)^2+(10 \:m)^2\\\\\\:\implies\sf (AC)^2= 576\:m^2+100\:m^2\\\\\\:\implies\sf (AC)^2=676 \:m^2\\\\\\:\implies\sf AC= \sqrt{676 \:m^2}\\\\\\:\implies\sf AC = \sqrt{26 \:m \times 26 \:m}\\\\\\:\implies\underline{\boxed{\sf AC = 26 \:m}}

\therefore\:\underline{\textsf{Man is \textbf{26 m} away from starting point}}.
