Question

Find the distance between (3,4) and (7,5).

Answer 1

Answer: 4.123106

Explanation:

Find the difference between coordinates:

(x2-x1) = (7 - 3) = 4

(y2-y1) = (5 - 4) = 1

Square the results and sum them up:

(4)2 + (1)2 = 16 + 1 = 17

Now Find the square root and that's your result:

Exact solution: √17 = √17

Approximate solution: 4.1231
