Distance = square root ((x2 - x1)^2 + (y2 - y1)^2)
(2,0)...x1 = 2 and y1 = 0
(5,-1)..x2 = 5 and y2 = -1
sub and solve
d = sqrt ((5 - 2)^2 + (-1 - 0)^2)
d = sqrt ((3^2) + (-1^2))
d = sqrt (9 + 1)
d = sqrt 10 <==
Answer: A
Explanation: If the side length is 5, than 5•5=25
0.abc
a is tenth
look at thousandths place (b) to round
if b is more than or equal to 5, round b up 1
if b is less than 5 then ignore
0.232
b is 3
3<5
remain
0.2
