Answer:

Option A. [tex]4.3\ cm[/tex]

Step-by-step explanation:

we know that

To find the diagonal of the rectangle apply the Pythagoras Theorem

Let

D-----> the diagonal of rectangle

L----> the length of rectangle

W---> the width of rectangle

so

[tex]D^{2}=L^{2}+W^{2}[/tex]

substitute the values

[tex]D^{2}=3.6^{2}+2.4^{2}[/tex]

[tex]D^{2}=18.72[/tex]

[tex]D=4.3\ cm[/tex]
