Question:

What is the area, in square inches, of a square piece of carpet that measures 6 feet 2 inches on a side?

A 5,476
explanation

Since the problem asks for the area in square inches, you need to express the length of the side in inches. A length of 6 feet 2 inches is 6 × 12 + 2 = 72 + 2 = 74 inches. The area, then, is 74 × 74 inches = 5,476 square inches.
