P sebenarnya = 36 x 1000 = 36000cm = 360 m
l sebenarnya = 25 x 1000 = 25000cm = 250 m

keliling = 2x(360 + 250) = 1220 m
luas = 360 x 250 = 90000 m2

Skala 1 : 1000
25 cm = 25 * 1000 = 25000 cm = 250 m
36 cm = 36 * 1000 = 36000 cm = 260 m
luas = p * l = 250 * 360 = 90000 m kuadrat
keliling = 2(p+l) = 2(250+360) = 1220 m
ralat :
36 cm = 36 * 1000 = 36000 cm = 360 m
iya makasih yaa
ok..
