1, U = (6, -4) , A = (11, 2)
On the x axis the distance is 11-6= 5 unit
On the y axis the sitance is 2-(-4) = 6 unit
With this you can imagine a trianle where 5 and 6 unit length are the basis and we are looking for the 3rd side.
5^2+6^2= x^2
61 = x^2
All the other questions are the same. You just need to find the distance between the two points.
