    Answer:

    700 cm^2

    Step-by-step explanation:

    The area of the picture + frame = L * W

    • L = 50 cm
    • W = 30 cm

    Area = 50 * 30

    Area = 1500

    =====================

    Area of inside area

    • L = 50 – 10 = 40 (Remember both ends have to be shortened)
    • W = 30 – 10 = 20 ( Remember again both ends have to be shortened)

    Area = L * W

    Area = 40 * 20

    Area = 800

    ======================

    Now the frame is going to take up the difference.

    Area Frame = Entirie area – inside area

    Area Frame = 1500 – 800

    Area Frame = 700
