Answer:

Marcia needs 32 inches of wood for the frame

Step-by-step explanation:

we know that

The perimeter of the rectangular frame is given by the formula

[tex]P=2(L+W)[/tex]

we have

[tex]W=4\ in[/tex]

[tex]L=3W[/tex]

substitute the value of W

[tex]L=3(4)=12\ in[/tex]

Find the perimeter

[tex]P=2(12+4)=32\ in[/tex]
