Reet of material for all 3 hat and scarf sets.

34.5 feet of material for 3 hat and scarf sets.

Step-by-step explanation:

First, we need to convert all measurements to the same unit: foot. (Because the answer is requested in foot)

1 yard is equal to 3 feet, and 1 inch is equal to 0.08333 feet.

3 yards are equal to 9 feet, and 30 inches are equal to 2.5 feet.

We need 3 sets of hat and scarf, so this means that we need 3 hats and 3 scarfs.

One scarf needs 9 feet of material, so 3 scarfs need 27 feet.

One hat needs 2.5 feet of material, so 3 hats need 7.5 feet.

In total, 3 scarfs and 3 hats need 27+7.5=34.5 feet of material.
