Answer:
The perimeter is 10 units
Step-by-step explanation:
we know that
The tile is shaped like a rectangle
so
The perimeter of a rectangle is given by the formula
[tex]P=2(L+W)[/tex]
where
L is the length
W is the width
In this problem we have
[tex]L=4\ units\\W=1\ unit[/tex]
substitute in the formula
[tex]P=2(4+1)=10\ units[/tex]
