a. Titik (10, 20) dan (13, 16)
= Jarak √{(20-16)⊃2; + (10-13)⊃2;}
= √{4⊃2; + (-3)⊃2;}
= √(16+9)
= √25
= 5 satuan
b. Titik (15, 37) dan (42, 73)
= Jarak √{(73-37)⊃2; + (42-15)⊃2;}
= √(36⊃2; + 27)⊃2;
= √(1296+729)
= √2025
= 45 satuan
c. Titik (-19, -16) dan (-2, 14)
= Jarak √{(14-(-16))⊃2; + (-2-(-19))⊃2;}
= √(30⊃2; + 17)⊃2;
