Tolong dibantu ya kak, pake caranya no 11 sama 14 :)

11. skala = peta : sebenarnya
= 5 cm : 40m
= 5cm : 4000cm
= 1 : 800
14. peta = sebenarnya / skala
= 80 m / 500
= 8000cm / 500
= 16 cm

11. S = JS × JP
S = 5 cm× 40 m
S = 0.05 × 40
S = 2
jadi skalanya pd gambar adl 1: 2
14. JS = S / JP
JS = 500 / 80 m
JS = 500/8000
JS = 16
Jadi panjangnya kebun pd gambar adl 16 Cm
