Answer:
169 square feet/169 feet²
Step-by-step explanation:
We know that Shauna wants to cover her whole floor with the carpet. The floor is 2D, so we're looking for an area (LxW). We know the length of one side, which is 13. If we reread the question, she specified that her room is square. That means that the sides are equal, so if one side is 13, so is the other. If you put in 13 for L and 13 for W in our area formula, the result is 169. They aren't looking for a number, though. They want an area, so the unit is going to be squared. The unit given is feet, so the answer is 169 square feet, or 169 feet², depending on what format your teacher wants.
