Mapel = MatematikaBab = Skala
Diketahui :
Luas persegi pda denah = 400 cm²
Skala = 1 : 160
Sisi persegi tanah pada denah
S² = L. Persegi
S² = 400 cm²
S = √400 cm²
S = 20 cm
Sisi Persegi tanah Sebenarnya
= Sisi pda denah : Skala
= 20 cm : 1/160
= 20 cm x 160
= 3200 cm
= 32 m
Keliling tanah = 4 . sisi
Keliling tanah = 4 . 32 m
Keliling tanah = 128 m
Semoga membantu :)
