A5 inch × 7 inch photograph is placed inside a picture frame. both the length and width of the frame are 2x inches larger than the width and length of the photograph. which expression represents the perimeter of the frame?

The options are;
a)4x+12
b)8x+24
c)2x^4+24
d)4x^2+24x+35


dimensions of the photograph 
length - 7 inch 
width - 5 inch
dimensions of the photo frame is 2x larger than both width and length 
length - 7 + 2x
width - 5 + 2x
the perimeter is sum of all 4 sides 
Perimeter = 2(7 + 2x) + 2(5 + 2x)
                 = 14 + 4x + 10 +4x
                 = 24 + 8x
correct answer is b
