Question

A rectangular floor is 7 yd long and 3 yd wide. Heatherwants to tile the floor with tile sold by the square foot.Use the facts to find the area in square feet.Conversion facts for length1 foot (ft) = 12 inches (in)1 yard (yd) = 3 feet (ft)1 yard (yd) = 36 inches (in)2Х5?

Answer 1

We need to convert the given measures from yard to feet. Since 1 yard is equal to 3 feet, we have

$\begin{gathered} 7yd=7yd\times(\frac{3ft}{1yd}) \\ \text{then} \\ 7yd=21ft \end{gathered}$

similarly, for the wide, we have

$\begin{gathered} 3yd=3yd\times(\frac{3ft}{1yd}) \\ 3yd=9ft \end{gathered}$

Since the area of a rectangle is wide times length, the area is

$\begin{gathered} A=\text{wide}\times length \\ A=9ft\times21ft \\ A=189ft^2 \end{gathered}$

Therefore, the area is equal to 189 square feet
