Question

A rectangular placemat is 18 inches long and 12 inches wide. What is the area of ​​this tablecloth in square inches?

a. 216
b. 60
c. 54
d. 900

Answer 1

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.

Answer 2

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.
