Answer:
We need to find the ratio of the width of the actual picnic area to the width of the picnic area in the drawing. Since 1 yard is equal to 36 inches, we can convert 33 yards to inches by multiplying by 36:
33 yards x 36 inches/yard = 1188 inches
So the ratio is:
1188 inches / 22 inches = 54
This means that 1 unit in the drawing represents 54 units in real life. Therefore, the scale of the drawing is 1:54.
