Answer
Die oppervlakte kan bereken word met die formule:
extOppervlak=extLengte(L)imesextBreedte(B)
Gegewe dat die lengte 2 cm is en die breedte 1.5 cm, die berekening sal wees:
Oppervlak = 2extcmimes1.6extcmimes100=3200extm2.

Answer
Die magnetiese peiling kan bereken word met die formule MP=WP+MD. As die ware peiling 190° is, dan is die magnetiese peiling MP=190°+17°10′=207°10′.
