Distance formula is like pythagoren ahtoerem
D= $\sqrt{(7-2)^{2}+(5-8)^{2}}$
the distance between oints (x1,y1) and (x2,y2) is
D= $\sqrt{(x2-x1)^{2}+(y2-y1)^{2}}$
(2,8) and (7,5)
D= $\sqrt{(7-2)^{2}+(5-8)^{2}}$
D= $\sqrt{(5)^{2}+(-3)^{2}}$
D= $\sqrt{25+9}$
D= $\sqrt{34}$
apxos
D=5.8309....

round
D=5.8 units
