1.skala 1 : 1.200.000
t= 4 x 1.200.000 =4.800.000 cm = 48 km
a=2 x 1.200.000 =2.400.000 cm = 24 cm
b = 5 x 1.200.000 = 6.000.000 cm = 60 km
L sebenrnya =1/2(a+b)t = 1/2(24+60) x 48 =1/2x84 x 48 = 2016 km²
2.skala 1 :200
ukuraan pd peta :
p = 105 m =10500 cm ---> 10500/200 =52,5 cm
l= 68 m = 6800 cm ---> 6800/200 = 34 cm
L =pl = 52,5 x 34 =1785 cm²
