Answer:
Here is your answer dear
Explanation:
Using the lens formula; -1/u+1/v=1/f
rearranging, 1/v=1/18-1/27=1/54
hence 1/v=1/54.
To get the position of the image, V, find the reciprocal of 1/54.
Hence, v=54cm.
To obtain the size and nature of image,
use magnifcation formula; hi=V/u*h=54/-27*4=-8.0cm.
Therefore, size of image is 8cm.
Nature=virtual image.
