Distance Between Points

Given 2 coordinate points:

(a,b) and (c,d)

To find the distance between the points follow this formula.
Note: Sometimes your calculator is not as smart as you are and so I advise you to work through the problem as far as you can without the use of your calculator.

Take the Square Root of the quantity ((a - c)^2 + (b - d)^2)

Note: ^2 means square the quantity.

Example:

A(-12,20)
B(5,-18)

Square Root of the quantity ((-12 - 5 )^2 + ( 20 - -18 )^2)

Square Root of the quantity ((-17)^2 + (38)^2)

Square Root of the quantity (289 + 1444)

Square Root of the quantity (1733)

approximately = 41.629 or 41.63

Note: Please round your answers to at least the 2nd decimal place.
