3u + 4u + 2u = 9u
9u = 90
1u = 90/9 = 10
since black is 2u ( from the ratio given)
2u = 10 x 2 = 20
Answer : 20cm of the pole is painted black.

Answer:
As you can see Rectangle L M NO and Rectangle L'M'N'O' are such that
1. Size of Rectangle L M NO > Size of Rectangle L'M'N'O'
2. Sides of, means length and breadth of Rectangle L M N O is not in proportion to Rectangle L'M'N'O'. i.e
3. Out of four possibilities given :
, Reflection and Rotation is not possible because in all the three cases Pre-image and image are not congruent or similar.
As in,Rectangle LMNO →when length and breadth get reduced by scale of 2 and 0 and Dilation by scale factor of< 1 we get Rectangle L'M'N'O'.Centre of dilation may be other than origin.
So, Stretching of preimage i.e Rectangle L M NO→ means Shrinking has taken place to get image Rectangle L'M'N'O'.As shrinking is not an option.
So, Dilation by a factor less than 1, center of dilation other than origin has taken place.
