Given
The length of the top table is 15 in.
The width of the top table is 7.5in.
Explanation
To determine the diagonal in order to be perfectly rectangle.
Apply the Pythagoras theorem, in the given rectangle.
[tex]Diagonal\text{ }^2=Length^2+width^2[/tex]
Substitute the values
[tex]\begin{gathered} \text{Diagonal}^2=15^2+7.5^2 \\ \text{Diagonal}^2=225+56.25 \\ \text{Diagonal}^2=281.25 \end{gathered}[/tex]
So, for the diagonal of the top of the table need to be in order for it to be a perfect rectangle , round to the nearest tenth is
[tex]\begin{gathered} \text{Diagonal}=\sqrt[]{281.25} \\ \text{Diagonal}=16.77in \end{gathered}[/tex]
Answer
The diagonal of the top of the table need to be in order for it to be a perfect rectangle is 16.8 in.
