Mia is building a three-sided shelter for her action figures. The shelter will

resemble a rectangle with one of the long sides removed. She has boards that
measure 36 inches, 39 inches, and 42 inches in length; all the boards are the
same width. Mia will need to convert some of these measurements into other
imperial units to build the shelter the way she wants. Answer the following
questions. Show your work. Record your answers below. What is the width of the shelter, measured in feet?

To find the width of the shelter in feet, we need to convert the measurement from inches to feet.

Given that the boards are of the same width, we can assume that the width of the shelter is the same as the width of the boards.

Let's convert the width from inches to feet:

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

Since all the boards are the same width, the width of the shelter is 3 feet.
