Morphology
carpenter's + square
The meaning is directly derivable from the constituents: 'carpenter's' indicates belonging or use by a carpenter and 'square' names the right-angled measuring tool. This genitive+noun composition is a standard, compositional pattern (profession + tool), so a B1 learner who knows the parts will readily infer the MWE's meaning.
Etymology
Carpenter's square is an L-shaped metal tool carpenters use to mark and check perfect corners. Its two arms form a right angle, so the name joins carpenter and square — carpenters used it to make things 'square', and that's why it means a tool for marking right angles.
