Tolong jawab nomor 9 ya

skala 1 :1400

p sbnrnya =4,5 x 1400 =6300 cm =63 m
l sbnrya =3,5 x 1400 =4900cm = 49 m

L sebnrnya =63 x 49
                   =3087 m²

jawab.A

panjang sebenarnya= jp: s
=4,5:1/1400
=4,5×1400
6300cm
63m

lebar sebenarnya= jp : s
= 3,5 : 1/1400
=3,5×1400
4900cm
49m

luas
=p×l
=63×49
=3087m²
