Answer:

Hey There!

Let's solve...

Here it is a rectangular floor with length =21 cm and width =15cm

So

$area = l * w \\ = 21 * 15 \\ = 315 {ft}^(2) \\ \\$

So now We need to convert it to yards square

$315ft^(2) * \frac{ {1yd}^(2) }{ {9ft}^(2) } \\ \\ = \cancel{315ft^(2)} \: ^(35) * \frac{ {1yd}^(2) }{ \cancel{9 {ft}^(2) }} \\ \\ = 35 {yd}^(2)$

So how this 9 ft^2 came??

Let's know

$ft \to \: yards \\ \\ 3ft = 1yd \\ \\ {3ft}^(2) = {1yd}^(2) \\ \\ \boxed{ {9ft}^(2) = {1yd}^(2)}$
