1a. Which board will Mia use for the length of the shelter, given that

1 foot = 12 inches?

36 inch

39 inch

42 inch

its 39 inches :]

what kind of shelter?

It could matter.

To convert the length of the shelter from inches to feet, we need to divide the length by the conversion factor of 12 inches per foot.

1a. Let's calculate for each option:

Option 1: 36 inches
36 inches / 12 inches per foot = 3 feet

Option 2: 39 inches
39 inches / 12 inches per foot ≈ 3.25 feet

Option 3: 42 inches
42 inches / 12 inches per foot = 3.5 feet

Therefore, Mia will use a 42-inch board for the length of the shelter.

To determine which board Mia will use for the length of the shelter, we need to convert the lengths given in inches to feet.

First, let's convert the lengths given to feet:

36 inches = 36 / 12 = 3 feet
39 inches = 39 / 12 = 3.25 feet
42 inches = 42 / 12 = 3.5 feet

Now we can compare the lengths in feet:

Mia has the following options:
- 3 feet
- 3.25 feet
- 3.5 feet

Based on the provided lengths, Mia will select the board that measures 3 feet for the length of the shelter.
