a square photograph measuring 8 inches by 8 inches is positioned within a 1 inch wide picture frame as best shown. select the best answer.
what is the combined area of the photograph and frame?

left and right sides of frame = 1 + 1 = 2 in
top and bottom sides of frame = 1 + 1 = 2 in
therefore the total length and width are:
L = 8 + 2 = 10 in
W = 8 + 2 = 10 in
recall that area of rectangle is given by
A = L*W
A = 10*10
A = 100 in^2
hope this helps~ :)
