Find the distance between the following pair of points

set a mid point at (-4,-4),length them ,triangle is formed

(3,-4)-(-4,-4)=7
(-4,-4)-(-4,-5)=1
the height is 7
the width is1

use pyth. theroem
7(7)+1(1)=x(x) (reason : Pyth. theroem)
49+1=x(x)
x(x)=50
x=70.71067812

√ ((3-(-4))^2+(-4-(-5)^2)
=√(49+1)
=√50
=7.07

(3,-4) = 3-(-4) =7
(-4,-5) = -4-(-5) = 1
