Answer 2

Here , we are given with a square which has 100 small squares in it , now we have to use two colours to represent 0.3 × 0.9 on it . So , now let's proceed :-

${:\implies \quad \sf \dfrac{3}{10}\times \dfrac{9}{10}}$

${:\implies \quad \sf \dfrac{27}{100}}$

Now , here , we have to colour 27 boxes with a colour and the left (100-27) = 73 boxes with another colour . Colour can be any of your choice
