tolong dibantu untuk mengerjakan soal ini ya, pake cara yg jelas

Js = Jp / Skala
Js = 25 / 1 : 50
Js = 25 . 50
Js = 1250 cm = 12,5 m

a.) K = 4.s
K = 4.(12,5)
K = 50 m

b.) L = s"
L = (12,5)"
L = 156,25 m"

Semoga membantu dan semoga bermanfaat...

Js=Jp/skala
= 25/1:50
= 25×50
= 1250 cm
Keliling = 4s = 4(1250) = 5000cm = 0,05km
Luas = s×s = 1250×1250 = 1562500 cm2 =0,00015625 km2
