1.Find the perimeter of the picture frame.
2. Find the perimeter and area of the picture
inside the frame.

Perimeter of the frame is 60 in and perimeter of the picture is 52 in. Area of the picture is 160 in²

Step-by-step explanation:

Perimeter of the frame = 2 (length + width)

                                      = 2(18 + 12) = 2 × 30 = 60 in

Length of the picture = 18 - 2 = 16 in

Width of the picture = 12 - 2 = 10 in

⇒ Perimeter of the picture = 2 (length + width)

                                            = 2 ( 16 + 10) = 2 × 26 = 52 in

Area = length × width

        = 16 × 10 = 160 in²

1; 35 is the ratio
