Bathroom tile

The wall in the bathroom has dimensions of 27 dm and 200 cm if we wanted to cover this entire wall with tiles in the shape of a square with a side length of 10 cm. How many tiles can fit in the height, and how many in the length of the wall in the bathroom? How many tiles will the whole wall have?

Final Answer:

y =  20
x =  27
t =  540

Step-by-step explanation:

$$\begin{gathered} a=27\text{dm}\to \text{cm}=27\cdot 10\text{cm}=270\text{cm} \\ b=200\text{cm} \\ c=10\text{cm} \\ y=b/c=200/10=20 \end{gathered}$$

$x=a/c=270/10=27$

$t=x\cdot y=27\cdot 20=540$
