Final answer:
The area of Mr. Hayes' classroom is 4800 square inches, which converts to approximately 33.33 square feet after dividing by 144, the number of square inches in one square foot.
Step-by-step explanation:
Mr. Hayes' classroom dimensions are provided in inches, with a height (presumably the length of one of the walls) of 60 inches and a base (or width of the opposite wall) of 80 inches. To calculate the area of the classroom, which is a rectangle, we multiply the length by the width.
Therefore, the area is 60 inches * 80 inches = 4800 square inches. However, since the area of a room is typically given in square feet, we can convert the area to square feet. There are 144 square inches in one square foot, so 4800 square inches is equal to 4800 / 144 = 33.33 square feet.
Thus, the area of Mr. Hayes' classroom is approximately 33.33 square feet.
