what is the combined area of the photograph and frame?

  • algebra - ,

    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~ :)
