The area of the chalkboard can be calculated using the formula:


A=l* w

From the question, the following parameters are given:


\begin{gathered} l=1\text{ yard} \\ w=2\text{ yards} \end{gathered}

Therefore, the area is calculated to be:


\begin{gathered} A=1*2 \\ A=2\text{ square yards} \end{gathered}

If the board costs $34.09 per square yard, the cost of a 2 square yard board will be:


\Rightarrow2*34.09=68.18

The chalkboard costs $68.18.
