Question

A science fair poster is a rectangle 3ft long and 2ft wide. Some of the entry rules for the fair refer to the area of the poster in square inches. Use the facts to find it's area in square inches.

Answer 1

864 in²

Step-by-step explanation:

First, we need to convert feet to square inches. Since 1 foot is equal to 12 inches, we can convert the width and length of the rectangle as

`\begin{gathered} 3\text{ ft}*\frac{12\text{ in}}{1\text{ ft}}=36\text{ in} \\ \\ 2\text{ ft}*\frac{12\text{ in}}{1\text{ ft}}=24\text{ in} \end{gathered}`

Then, the area of the poster in square inches is

Area = Length x width

Area = 36 in x 24 in

Area = 864 in²

Therefore, the answer is 864 in²
