hy tolong donk bsk dikumpul no 11 sampai 20 please yg jawab nanti akun brainly nya di follow

11. panjang sebanranya = 50 m = 500 cm
panjang pada peta = 25 cm
skala = jp : js
= 25 : 500
= 1 : 20

12. perbandingan = 2 : 3 : 4

sudut 1 = 2/9 x 180 = 40°
sudut 2 = 3/9 x 180 = 60°
sudut 3 = 4/9 x 180 = 80°
sudut terbesar = b. 80°

13. ukuran = 4 x 6
panjang stlh diperbesar = 18 cm
perbesaran = 18 : 6 = 3kali
lebar = 4 x 3 = 12 cm (C)

14. DSTTT
