Well first you have to find the dimensions of the frame, you can find that by subtracting the dimensions of the photo from the whole dimensions so it will be the

length of the photo and frame - length of the photo = 25- 20 = 5 length of the frame

Now the width of the photo and frame - width of the photo = 20 -16 = 4 the width of the frame

ok so the Area of the rectangle = width x length = 4 x 5 = 20 the Area of the frame

Hope that helps
