Reed is buying wood flooring for his rectangular kitchen. The dimensions of his kitchen are 12 feet by 10 5/12 feet. The cost of the wood flooring he likes is $3.90 per square foot.How much will the wood flooring cost to cover his kitchen floor?A$360.38B.$469.63С$487.50D$491.40

Answer 1

Given the area of a rectangle,

$\begin{gathered} \text{Area of Rectangle=l}\times b \\ \end{gathered}$$\begin{gathered} \text{Length, l=12ft} \\ \text{Breadth, b= 10}\frac{5}{12}ft \end{gathered}$$\begin{gathered} \text{Area}=12\times10\frac{5}{12} \\ =12\times\frac{125}{12} \\ =125ft^2 \end{gathered}$

If the cost of a square foot is $3.9, then the cost of 125 square ft will be

$\begin{gathered} 125ft^2\times\text{ \ 3.9} \\ =\text{ \ 487.5} \end{gathered}$

Hence, the cost to cover his kitchen floor is $487.5

Option C is the correct option
