Given the formula for area of a triangle:

A = l x w

Where:

A is the area

l is the length

w is the width.

From the table, using the given areas and lengths, let's find the width.

To find the width, rewrite the formula for w:


w=(A)/(l)

Thus, we have:

For the widths using the values in the table, r


\begin{gathered} w=(A)/(l)=(192)/(16)=12 \\ \\ \\ w=(A)/(l)=(126)/(18)=7 \\ \\ \\ w=(A)/(l)=(120)/(12)=10 \end{gathered}

Therefore, the complete table is:
