Using Pythagoras rule
C² = a² + b²
Where
C= Hypotenuse side= 15.26 inches.
a= adjacent side= x
b= opposite side= 13 inches
a² = b²+ C²
= ( 15.26²- 13²)
=(232.86 - 169)= 63.87
a= √63.87= 8inches
Which means the "x" side is 8inches
One of the length of the side is 13 inches, the other length is 8inches, which implies that the geometry is a "rectangle not square because the length of the sides are not equal.
