Question

Sunita and her friend were standing at opposite corner of rectangular park of size 120m×50m for meeting her friend sunita followed the shortest route find the distance covered by sunita in doing so

Answer 1

130 metres 
use hypotneuse rule 

Answer 2

yes answer is 130 because the shortest distance from one corner of the rectangle to the another corner will be its diagonal

and we can simply find the diagonal
120*120+50*50 (hypotenuse theorem)
14400+2500
16900
square root of this is
130
