4*9=36 in
To find the perimeter of a rhombus, you need to add the lengths of all four sides. Given that each side of the rhombus is 9 inches long, you can multiply this value by 4 to get the perimeter.
So, the perimeter of the rhombus with sides each 9 inches long is:
9 inches (side 1) + 9 inches (side 2) + 9 inches (side 3) + 9 inches (side 4) = 36 inches.
Therefore, the perimeter of the rhombus is 36 inches.
