...from a medieval European military handbook.
An army wishes to scale a 24-foot high castle turret. If the turret lies across an 18-foot wide moat, how long must the army’s ladder be?
...from the Cairo Papyrus, an Egyptian mathematical papyrus dating from about 300 BCE.
A ladder of length 10 cubits leans against a wall. If the foot of the ladder stands 6 cubits from the wall, how high up the wall does the ladder reach?
...from an ancient Mesopotamian clay tablet from the Old Babylonian period (1900-1600 BCE).
A beam of length 30 units stands vertically against a wall. As the top of the beam slides down the wall, the bottom of the beam slides away from the wall. If the top of the beam slides 6 units down the wall, how far does the bottom of the beam slide away from the wall?
