For example, I found this problem, from the 2019 exam, worthwhile:

A quadrilateral has its vertices (listed in clockwise order) as

(–6.94, –1.2), (–5.16, 3.84), (3.4, 2.18), and (2.46, –6.72).

Give the area of this quadrilateral.

Surveyors among you may recognize this one. A short RPL program on the 50g solves it quickly.
