The location of the doorknob is
Solution:
Door knob ( - 3 , - 1)
Medicine ( 2 , - 1)
pottery jug (2, 4)
doorknob and the medicine bottle
= √(-3 - 2)² + (-1-1)²
= 5
1 unit = 5 m
=> 5 x 5 = 25 m
medicine bottle and pottery jugs
= 5 unit
= 25 m
doorknob and the pottery jug
√50 = 7.07 m
= 7.07 x 7
= 35.35 m
The co-ordinates of jug and medicine bortle respectively are
(2, 4) (2.-1)
The location of the doorknob is (-3 , -1 )
