Ok so the first part is asking you what the perimeter of the picture itself is.
The picture is 5in by 7in SO you add 5+5+7+7=24 So the perimeter of the pic is 24 inches.

Now part b

So the frame is one inch thick
This mean that the sides are now 2 inches longeron each side

 SO we have 7+7+9+9=32

So the perimeter is 32

I hope that helped If you dont understand something ask and i will reexplain ;)

a. Perimeter of the Picture would be all the sides added up all together. Since it's a 5in. by 7in. picture we know that two sides equal 5 inches and the other two sides equal 7 inches.
5+5+7+7=
10+14=
24 inches

b. If I'm understanding correctly then ...
There is a 1 inch between the picture and the frame.
Thus, each side of the picture has two added inches (one inch on the right and left side)

So, the sides with 5 inches now have two inches extra resulting in its length becoming 7 because 5+2=7
The other two sides with 7 inches now have two extra inches as well. Now becoming nine inches in length.

The frame is determined to be a 7in. by 9in.
Just like we did with the picture, we know add up all the sides.
7+7+9+9=
14+18=
32inches

Hope I didn't mess up for your sake!
