Answer:
see the explanation
Step-by-step explanation:
Let
L ---> the length of rectangle in cm
W ---> the width of rectangle in cm
The area of rectangle is
[tex]A=LW[/tex]
[tex]A=991\ cm^2[/tex]
so
[tex]991=LW[/tex] ---> equation A
we know that
Prime numbers only have factors of 1 and themselves.
So a rectangle with an area of 991 cm² can only be either
[tex]W=1\ cm, L=991\ cm[/tex] or [tex]L=1\ cm, W=991\ cm[/tex]
