Q-10. Sumit walks 20 m. to the East from point ‘A’, Then walks 20 m. in South-West direction. Then walks 20m in North-West direction and reaches at point B. Find distance b/w A and B.?
(a) O m.
(b) (20√2-1) m
(c) 20 m.
(d) 20√2 m.
[showhide type="links10" more_text="View Answer and Solution " less_text="Hide answer "]
Answer: (b) (20√2-1) m
Solution:
BC =[latex] \sqrt{(CD)^{2}+ {(BD)^{2}}} [/latex]
BC =[latex] \sqrt{(20)^{2}+ {(20)^{2}}} [/latex]
=[latex] \sqrt{400+400}[/latex]
= [latex]\sqrt{800}[/latex]
=[latex] 20\sqrt{2}[/latex]m
Then AB
= BC - AC
=[latex] 20(\sqrt{2-1})[/latex]m
