Question 381140: The outside dimensions of a picture frame are 3 feet by 29 inches. If its inside dimensions are 1 2/3 feet by 22 inches, what is the area of the frame?
I've tried to do length times width on both sizes but the answer is a multiple choice and none of the answers I've come up with are a choice. Here's what I've tried...outside-- 36 inches x 29 inches= 1044 inches or 87 feet
inside-- 20 inches x 22 inches= 440 inches or 36.66 feet
answer choices are A) 137.33 ft2 B) 616 in2 C) 144.67 ft2 D) 604 in2
