Perimeter= 2(l) + 2(w)

l = length
w = width

Answer 8

Both the y-axis for each coordinate lying horizontal from each other is the same.
(2,5) and (5,5) -- in this case it is 5
(2,3) and (5,3) -- in this case it is 3

So just subtract the larger x-axis from the smaller x-axis of the other coordinate.
e.g distance from (4,5) to (7,5) would be 3 units (7 - 4 = 3)
