Final answer:

The perimeter of a pentagon with all sides measuring 9 inches is 45 inches, calculated by multiplying the side length by the number of sides.

Step-by-step explanation:

The perimeter of a polygon is the total length around it, which is found by adding up the lengths of all its sides. For a pentagon with all sides equal to 9 inches, the perimeter would be the sum of all five sides. Using the formula for the perimeter (P) of a pentagon, which is P = side length × number of sides, we calculate it as follows:

P = 9 inches × 5 sides = 45 inches.

Therefore, the perimeter of the pentagon is 45 inches.
