Apicture frame is 16 inches long and 9 inches tall. it is 2 inches wide on all 4 sides. what is the area of the picture
frame?

The area of the picture frame would be 84 in2

Why?

The area of frame is the total area inside something and the area is basically length times width. The inner length would be 16-2-2 and keep in mind this is on BOTH sides.

If not, it can be 12.

The width or the height would be 9-2-2 which equals 5.

So the area is 12 x 5 = 60. So for the outer one be do 16 by 9 so..16 x 9 = 144 and so it would be 144 - 60 = 84.

Hope this helped! - Kana
