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:
- Step 1: Find the perimeter of the frame when width = 12 in and length = 18 in
Perimeter of the frame = 2 (length + width)
= 2(18 + 12) = 2 × 30 = 60 in
- Step 2: Find the perimeter of the picture inside the frame.
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
- Step 3: Find the area of the picture.
Area = length × width
= 16 × 10 = 160 in²
