What is the perimeter of this tile?

10 in.

Step-by-step explanation:

The perimeter of a rectangle is the sum of the lengths of the 4 sides.

perimeter of rectangle = length + length + width + width

Opposite sides of a rectangle have the same length. Since one side measures 4 inches, the opposite side also measures 4 inches. Since one side measures 1 inch, the opposite side also measures 1 inch. There are two 4-inch sides and two 1-inch sides.

perimeter = 4 in. + 4 in. + 1 in. + 1 in.

perimeter = 10 in.
