Question

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

Answer 1

let this be the rect. where l= 120 m
w = 50 m
we need to find d
So, by Pythagoras theorem
b^2 + p^2 = h^2
l^2+w^2=d^2
120^2+50^2= d^2
14400+2500= d^2
16900 = d^2
d = √16900
d = 130 m
So,the answer is 130m.

Answer 2

let triangle abcd and they are standing at a and c so in triangle abc 
By pythagoras theorem
ac= √(120)²+(50)²m⇒√14400+2500m⇒√16900m⇒130m
130m is shortest route
