Answer:


A_f=470ft


P_f=88ft

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
