State the sign convention used to measure the length of the image and the object.
(N/A) According to the Cartesian sign convention for spherical mirrors and lenses:
$1$. All distances measured perpendicular to the principal axis and in the upward direction (above the principal axis) are taken as positive (+).
$2$. All distances measured perpendicular to the principal axis and in the downward direction (below the principal axis) are taken as negative (-).
