What is the perimeter of the rectangle whose base is 5 inches and whose height is 12 inches?

The perimeter of a rectangle is given by the formula:

Perimeter = 2(base) + 2(height)

Plugging in the values:
Perimeter = 2(5) + 2(12)
Perimeter = 10 + 24
Perimeter = 34

Therefore, the perimeter of the rectangle is 34 inches.
