Tiyane makes a scale drawing of the parallelogram. The longer side of the parallelogram is 22.5 inches in her drawing. What is the length of the parallelogram’s shorter side in Tiyane’s scale drawing? the scale factor is 9 inch 3 inch

Since the scale factor is 9 inches to 3 inches, that means the scale is 3:1 (9 inches on the actual parallelogram corresponds to 3 inches on the scale drawing).

The actual parallelogram has sides of 45 inches and 9 inches. The longer side of the scale drawing is 22.5 inches, so we can find the length of the shorter side of the scale drawing by using the scale factor:

Shorter side of scale drawing = (22.5 inches) * (1/3)
Shorter side of scale drawing = 7.5 inches. Answer: \boxed{7.5}.
