Answer is C as 5 is the length of one side of the square.
A=s^2
5^2=25

All y-coordinates are different therefore it must be a tilted square. The major clue, in this case, is that there are two pairs of points with y-coordinates that have the difference of one: 0, 1 and 4, 5 have the same difference and they make a pair of parallel lines. You can also pair the points with y-coordinates of 0, 4 and 1, 5 and make up the other pair of parallel lines. Therefore the length is sqrt(4^2 + 1^2) = sqrt(17) and the area is 17.

Another method could be the bigger square PQRS - 4 right triangles i.e. 5*5 - 4*(0.5 * 1 * 4) = 17

Can someone please explain the solution ?
I am not able to understand how do we get the sqr(1) in sqroot(sqr(4) + sqr(1)) in the above mentioned solutions.
