    if the lens is assumed to just flip and not distort the picture this is similar triangles

    210 cm = 2.1 m right?

    first you need to convert the meters into centimeters i think that would be easier. so that would be 210 meter. i will draw a picture to help with the rest.

    then you take 168 by 210 ---- ---- x 3 you simply cross multiply and divide so it will be 210x by 504. you then divide 210 to get "x" alone which will come out to be 2.4 2.4 will be what x equals
