Answer:
Hey There!
Let's solve...
Here it is a rectangular floor with length =21 cm and width =15cm
So
![area = l \times w \\ = 21 \times 15 \\ = 315 {ft}^{2} \\ \\](https://tex.z-dn.net/?f=area%20%3D%20l%20%5Ctimes%20w%20%5C%5C%20%20%3D%2021%20%5Ctimes%2015%20%5C%5C%20%20%3D%20315%20%7Bft%7D%5E%7B2%7D%20%5C%5C%20%20%5C%5C%20%20)
So now We need to convert it to yards square
![315ft^{2} \times \frac{ {1yd}^{2} }{ {9ft}^{2} } \\ \\ = \cancel{315ft^{2}} \: ^{35} \times \frac{ {1yd}^{2} }{ \cancel{9 {ft}^{2} }} \\ \\ = 35 {yd}^{2}](https://tex.z-dn.net/?f=315ft%5E%7B2%7D%20%5Ctimes%20%20%5Cfrac%7B%20%7B1yd%7D%5E%7B2%7D%20%7D%7B%20%7B9ft%7D%5E%7B2%7D%20%7D%20%5C%5C%20%20%5C%5C%20%20%3D%20%20%5Ccancel%7B315ft%5E%7B2%7D%7D%20%20%5C%3A%20%5E%7B35%7D%20%20%5Ctimes%20%20%5Cfrac%7B%20%7B1yd%7D%5E%7B2%7D%20%7D%7B%20%5Ccancel%7B9%20%7Bft%7D%5E%7B2%7D%20%7D%7D%20%20%5C%5C%20%20%5C%5C%20%20%3D%2035%20%7Byd%7D%5E%7B2%7D%20%20)
So how this 9 ft^2 came??
Let's know
![ft \to \: yards \\ \\ 3ft = 1yd \\ \\ {3ft}^{2} = {1yd}^{2} \\ \\ \boxed{ {9ft}^{2} = {1yd}^{2}}](https://tex.z-dn.net/?f=ft%20%5Cto%20%5C%3A%20yards%20%5C%5C%20%20%5C%5C%203ft%20%3D%201yd%20%5C%5C%20%20%5C%5C%20%20%7B3ft%7D%5E%7B2%7D%20%3D%20%20%7B1yd%7D%5E%7B2%7D%20%20%5C%5C%20%20%5C%5C%20%20%5Cboxed%7B%20%7B9ft%7D%5E%7B2%7D%20%3D%20%20%7B1yd%7D%5E%7B2%7D%7D%20%20%20)

Answer:
5.57
Step-by-step explanation:
In order to find the are of a square you would use the equation <em>a²</em>. However, since you are finding the length of one side and its a square, you use the equation
. The area of this square is 31 sq in., so you would replace a with 31. The equation then becomes
<em>. </em>When out into a calculator, the answer is 5.567764... which rounded up to the nearest hundreth is 5.57.
Answer:
he expression is undefined where the denominator equals
0
, the argument of an even indexed radical is less than
0
, or the argument of a logarithm is less than or equal to
0
.
The domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined.
