Given is a square picture with side length of = 5f-4 inches
Also given is that framing adds 2 inches in the side length of the square picture.
So after framing the side length becomes 5f-4+2 = 5f-2 inches
Perimeter of the square is given as = side*4 or 4s
So perimeter of the framed picture will be given as =
[tex]4(5f-2)=20f-8[/tex] inches.
or perimeter can be found by adding the side length 4 times
[tex](5f-2)+(5f-2)+(5f-2)+(5f-2)=20f-8[/tex] inches
Hence the perimeter is 20f-8 inches.
