Answer 2

Answer:

Distance saved by Rumi = 117.157m.

Step-by-step explanation:

Rumi starts from her house and moves 200 m towards the north.

let us consider the above as the base of the right-angle triangle.

she turns left and moves further 200 m, let it be the other hand of right angle triangle

then the shortest distance will be the hypotenuse.= √(200² + 200²)

  =√(200 * 400)

 =20* 10√2

= 200√2

distance saved by Rumi = total distance covered by Rumi - the shortest distance.

distance saved by Rumi = (200 + 200) -200√2

                                        = 400 - 200√2

                                         =400-282.843 = 117.157m

therefore the distance saved by Rumi = 117.157m.
