The output f(x<span>) is sometimes given an additional name y by y = </span>f(x<span>). The example that comes to mind is the square root function on your calculator. The name of the function is \sqrt{\;\;} and we usually write the function as </span>f(x) = \sqrt{x<span>}. On my calculator I input </span>x<span> for example by pressing 2 then 5.</span>

How many yards<br> carpeting is needed to cover a 60 feet length room and 40 feet width ​
Bad White [126]

Answer:

266 \frac{2}{3} yards

Step-by-step explanation:

1. Approach

First, convert the dimensions of the room from feet to yards. Remember, the conversion rate between feet and yards is, 3feet=1yard. Next, find the area of the room by multiplying the length by the width.

2. Convert the unit of measurement

The measurement unit is given in feet, one must convert it into yards. The conversion rate between yards and feet is, 3feet=1yard.

60feet=20yards\\\\40feet=13\frac{1}{3}yards

3. Find the area of the room

Now multiply the length by the width to find the area of the room.

20yards*13\frac{1}{3}yrads\\\\= 20 * \frac{40}{3}\\\\=\frac{800}{3}\\\\= 266\frac{2}{3}_{.}yards^{2}
