Question

What is the distance between the points (80, 55) and (20, 44)?

Answer 1

\[DISTANCE = \sqrt{(X _{1} - X _{2})²+(Y _{1} - Y _{2})²}\]

X1 = 80
Y1 = 55
X2 = 20
Y2 = 44

Answer 2

I did that but my answer was way to high.

Answer 3

sqrt((80-50)² + (55-44)²)
sqrt(30² + 11²)
sqrt(900 +121) = 31.953

Answer 4

is the correct answer 11?

Answer 5

I used the online distance between 2 points calculator and got 61 as the distance.

From above:

sqrt((80-50)² + (55-44)²) --> should be sqrt(80-20)^2 + (55-44)²
sqrt(60² + 11²)
sqrt(3600 +121)
sqrt(3721)
= 61
