Hint: the diagonals are equal.

So should I do x + 1 = 2x -3? Then x would be the length?

No, x will not be the length. Solve for x, then I'd explain how to do the rest.

Alright, thanks for helping me. I have x = 4.

Parth (parthkohli):

That's right! So the diagonal is x + 1 right? What's x + 1 here?

Remember that if x = 4, then x + 1 = 4 + 1.

x + 1 = 5
