48 ft. squared

60 ft.2
60 ft. squared

168 ft.2

Answer 1

The area of the frame can be calculated by subtracting the area of the inside rectangle from the area of the outside rectangle.

Area of the outside rectangle = 9 ft * 12 ft = 108 ft^2
Area of the inside rectangle = 6 ft * 10 ft = 60 ft^2

Area of the frame = Area of the outside rectangle - Area of the inside rectangle = 108 ft^2 - 60 ft^2 = 48 ft^2

So, the correct answer is:
48 ft^2
