Answer:
[tex](6W+6)\ in[/tex]
Step-by-step explanation:
we know that
The perimeter of a rectangle is equal to
[tex]P=2(L+W)[/tex] ----> equation A
where
L is the length
W is the width
we have
The length is 3 inches more than twice the width
so
[tex]L=2w+3[/tex] ----> equation B
substitute equation B in equation A
[tex]P=2(2W+3+W)[/tex]
Combine like terms
[tex]P=2(3W+3)\\P=(6W+6)\ in[/tex]
