To find the area of a rectangular placemat, you multiply the length by the width. In this case, the length is 18 inches and the width is 12 inches. Therefore, the area of the tablecloth is:

Area = Length × Width

Area = 18 inches × 12 inches

Area = 216 square inches

So, the correct answer is option a. 216.

In a rectangle, there are 2 pairs of congruent sides. Therefore, the area of a rectangle can be found using:


\text{A}=\text{l} * \text{w}

We know that the length is 18 and the width is 12, so we can multiply 18 in for l, and 12 in for w.


\text{A}=\text{18} * \text{12}

Multiply the numbers together


\text{A}=216

So, the area is 216 inches.
