To calculate the area of Marilyn's living room, we need to multiply the length by the width. Since you mentioned the length as "ft" without specifying a numerical value, I'll just represent the length as \( L \).
The formula for the area \( A \) of a rectangle is:
\[ A = \text{length} \times \text{width} \]
In this case, the width is 16 ft, so the area can be represented as:
\[ A = L \times 16 \]
If you provide the numerical value for the length \( L \), I can help you calculate the exact area.
