Question

Alica created a portrait that is 10 inches wide and 13 inches long she wants to put a frame that is 2 1/4 wide on each side

Answer 1

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

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