Given :

width of frame = 10.5 inches

length of frame = 20.75 inches

The amount of wood that she'll need for each photograph can be determined using the perimeter of the rectangular frame:

Perimeter(P) of rectangular frame:


\begin{gathered} P\text{ = 2l + 2w} \\ =\text{ 2 }*\text{ 20.75 + 2}*\text{ 10.5} \\ =\text{ 62.5 inches} \end{gathered}

Amount of wood needed in perimeter = 62.5 inches
