Apicture frame is 20 inches long and 7 inches tall. it is 1 inch wide on all 4 sides. what is the area of the picture frame? 26 in2 90 in2 140 in2 50 in2

The picture's length and width are 18 and 5. You subtract 2 instead of 1 because you are subtracting 1 on both sides of the frame.

The area of the picture is 90, and the area of the whole thing, picture and picture frame, is 20*7=140.

So, to find the area of just the picture frame, you subtract 90 from 140 to get 50in^2, which is your last answer choice.

the answer will be

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2
