Question

The distance between the points (3,5) and (5,7)is :

Answer 1

Distance between two points is whole root of X 1 - x to the whole square plus y 1 minus y to the whole square

This implies =>

Root of (3-5)^2 +(5-7)^2

This gives us =>

Root of 4+4 which is

2root2

Answer 2

the distance between the points (x,y) and (x*,y*) is given as

√(x*-x)2+(y*-y)2

here x=3 x*=5

y=5 y*=7

therefore,

d=√(5-3)2+(7-5)2

d=√(2)2+(2)2

d=√(4+4)

d=√8

d=2√2
