Answer:
The area of rectangle is 21 in^2
Step-by-step explanation:
we know that
The area of rectangle is equal to
[tex]A=LW[/tex]
where
L is the length
W is the width
In this problem we have
[tex]L=7\ in[/tex]
[tex]W=3\ in[/tex]
substitute
[tex]A=(7)(3)=21\ in^2[/tex]
The draw in the attached figure
therefore
The area of rectangle is 21 in^2
