A quadrilateral has vertices
P(3,5),Q(4,3),R(3,2),and S(5,4).
Find the lengths of the diagonals,to the nearest tenth?

Maybe rewording this question will help you out. Find the distance between two points:
a)(4,3) and (5,4)
b)(3,2) and (3,5)
I'm sure your teacher gave you this formula:
d = sqroot [(x2  x1)^2 + (y2  y1)^2]
where x and y are defined as (x,y) in the coordinate. x2 just mean the x in the second coordinate.
