According to the question,

  • 6 litres of paint is required to colour 900 m²

\\

Here, we need to find out the quantity of paint required to colour 4050 m²

\\

Paint | Surface Area

6 Litres | 900 m²

x Litres | 4050 m²

\\

Let us solve this question by using the concept of ratio and proportion.

 \boxed{6 : 900  \: :  :  \: x : 4050} \\  \\

 \implies \sf{900x = 4050 \times 6} \\  \\

 \implies \sf{x =  \dfrac{4050 \times 6}{900} } \\  \\

 \implies \sf{x = 27 \: litres} \\  \\

27 litres of paint is required for colouring 4050 m²

Answer:

27litres

Step-by-step explanation:

Given:-

6litres of paint required to paint 900 square metres surface.

To find:-

The quantity of paint that is required to colour 4050 m2 of a similar surface.

Solution:-

Let's use variation

x | 6 | ?

y | 900 | 4050

  • Here x various directly with y

\\ \sf {:}\longrightarrow x_1y_2=x_2y_1

\\ \sf {:}\longrightarrow 6\times 4050=9000\times y_1

\\ \sf {:}\longrightarrow y_1=\dfrac{6\times 4050}{900}

\\ \sf {:}\longrightarrow y_1=\dfrac{24300}{900}

\\ \sf {:}\longrightarrow y_1=27
