"µm" is the scientific symbol for micrometer
An image formed by a convex lens is described by the lens equation 1/u+1/v=1/f, where u is the distance of the object from the lens, v is the mage distance from lens and f is the focal length of the mirror. The question states that f=10cm and u=15cm, This can be substituted in the lens equation as follows: 1/15+1/v=1/10 1/v =1/30 V=+30 Magnification =v/u =30/15=2. The positive sign of v means the image is real, inverted and it on the opposite side of the object. Solution: The image is twice the same size as the object, real, inverted and on the opposite of the object.
I believe it can be used for any lens. Just be sure to use the correct sign. Check the "lensmaker's equation" in Wikipedia, and the comments about what sign to use.

You have to put the square sign when you use area and the cubic sign when you use volume. Area= Length times Width Volume= Length times Width times Height

Parallel. looks like this: =
Starting at about the wrist, the pointed index finger moves up the length of the arm.
An Octagon. ( see a stop sign ).
Seeing as the area = 158 = the length of 1 side squared. One side = the square root of 158 = about 12.5698 feet
