Tolong jawab ya nomor 9 & 10 pakai caranya ya!!

panjang sebenarnya=jp×s=9×2500
=22500cm=225m
lebar sebenarnya=jp×s=6×2500=15000cm
=150m
luas sebenarnya=225×150=33750m2

9. 9×2.500 = 82500/100 = 825
6×2.500 = 15000/100 = 150
Kll = 2×(p×l)
= 2×(825 + 150)
= 2× 975
= 1950m
10. 9×1000 = 9000/100 = 90
7×1000 = 7000/100 = 70
L = 90 × 70 = 4900m
