# 7th Geometry

posted by .

We are using the Pythagorean rule and I'm a little confused...
Solve each problem using a grid.
Dover is located at (1,2) and Goodlow is located at (5,7). How far apart are the 2 cities?

My answer is 6.40... am I doing this right? If not please explain. Thanks.

• 7th Geometry -

dist^2 = (5-1)^2 + (7-2)^2
= 16+25
= 41
distance = √41 = appr 6.40

You are correct.
