After going 80 m from his house towards east, a person turns left and goes 20 m, then turns right and moves 100 m, then turns left and goes 60 m, then turns left and goes 120m to reach the park. What is the distance between his house and the park?

Options

A. 80 metre
B. 120 metre
C. 20 metre
D. 100 metre

Answer

A

Explanation

`AF = sqrt((FG)^(2) + (AG)^(2))`
` = sqrt((80)^(2) + (300)^(2))`
` = sqrt(6400+90000)`
` = sqrt(96400)`
` = 310.48` = 300 meters .
