    Answer:

    A_f=470ft

    P_f=88ft

    Step-by-step explanation:

    From the question we are told that:

    Width of Portrait w=10inches

    length of Portrait l=13inches

    Frame each l_W=21/4inch each

     

    Generally the equation for area of portrait A is mathematically given by

    A=w*l\\A=10*13\\A=130m^2

    Generally the equation for Perimeter of portrait is mathematically given by

    P=2(w+l)\\P=2(10+13)\\P=46m

    Generally the equation for area of portrait  with frame is mathematically given by

    A=w_f*l_f

    where

    w_f=width of portrait with frame

    w_f=2*21/4+w\\w_f=2*21/4+10\\w_f=20.5ft

    l_f=Length of portrait with frame

    l_f=2*21/4+l\\l_f=2*21/4+13\\l_f=23.5ft

    Therefore Area of picture with frame

    A_f=w_f*l_f

    A_f=20.5*23.5

    A_f=470ft

    Generally the equation for Perimeter of portrait is mathematically given by

    P_f=2(w_f+l_f)\\P_f=2(20.5+23.5)\\P_f=88ft
