Final answer:
The question pertains to the area and perimeter of a rectangular room, suitable for Middle School Mathematics. The correct area is 216 sq. ft (Option A), but none of the given options correctly state the perimeter, which is calculated as 60 ft.
Step-by-step explanation:
The subject of this question is Mathematics, and it is tailored for a Middle School grade level. The question involves calculating the area and perimeter of a rectangular room.
The area of a rectangle is calculated by multiplying its length by its width. In this case, the area would be 18 ft × 12 ft, which equals 216 sq. ft. Therefore, option A) with an area of 216 sq. ft is the correct choice for area.
To find the perimeter of the rectangle, the formula is 2 times the length plus 2 times the width. That would be 2(18 ft) + 2(12 ft), which equals 36 ft + 24 ft, resulting in a perimeter of 60 ft. However, this is not one of the choices provided, which means there might be a typo in the question or options. None of the given options match the correct perimeter of 60 ft. After reviewing the available options, we must choose only one option for the correct answer to this particular question. Based on the calculations, the mention correct option in final answer is A) with an area of 216 sq. ft because it aligns with our calculated area of the rectangular room.
