The room is not in the shape of a square.
A line segment that connects any two non-adjacent vertices forms a square's diagonal. Two equal-length diagonals that are at right angles to one another make up a square.
One wall's length(a) is 13 inches.
Diagonal length (d) = 15.26 inches
When it comes to square,
Length of diagonal=[tex]\sqrt{2}[/tex] times the length of the side of the square.
[tex]d=\sqrt{2}*a[/tex]
Substituting the values,
Length of diagonal=[tex]\sqrt{2}*13[/tex]
=[tex]18.38[/tex] inches
The calculated length of the diagonal differs from the length that was provided in the question.
As a result, the room is not square-shaped.
