Answer:
[tex]L=\frac{15}{16}\ yd[/tex]
Step-by-step explanation:
The correct question is
Devon needs a wood board with an area of 5/16 square yard to complete a project. If the wood board is 1/3 yard wide, how long must the board be?
we know that
The area of a rectangle is equal to
[tex]A=LW[/tex]
where
L is the length
W is the width
we have
[tex]A=\frac{5}{16}\ yd^2\\\\W=\frac{1}{3}\ yd[/tex]
substitute
[tex]\frac{5}{16}=L(\frac{1}{3})[/tex]
solve for L
[tex]L=\frac{5}{16}(3)[/tex]
[tex]L=\frac{15}{16}\ yd[/tex]
