1. Luas taman asli = 300×154cm=46200cm2
=462m2
luas = 1/4 phi.d×d
462=1/4×22/7×d×d
462×4×7/22 = d^2
588 =d^2
d= 24, 25m
2. Jarak sebenarnya
= Jarak pd peta/skala
= 8 cm/1 : 1.125.000
= 8 cm x 1.125.000/1
= 9.000.000 cm
Jarak pd peta yg baru
= Jarak sebenarnya x skala
= 9.000.000 cm x 1/1.500.000
= 6 cm
