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

`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`
