Answer:
[tex]A=(n-3)2\ units^2[/tex]
[tex]A=(2n-6)\ units^2[/tex]
Step-by-step explanation:
we know that
The area of rectangle is equal to
[tex]A=LW[/tex]
where
L is the length of rectangle
W is the width of rectangle
In this problem we have
[tex]L=(n-3)\ units\\W=2\ units[/tex]
substitute
[tex]A=(n-3)2\ units^2[/tex]
Apply distributive property
[tex]A=2(n)-2(3)[/tex]
[tex]A=(2n-6)\ units^2[/tex]
