Pake cara ya,mau dikumpul besok.please

10. Luas layang” = 1/2.d1.d2
=1/2.(30+14).(8+8)
=1/2.44.16 = 352
11. K. Lingkaran = 2pr
2.3,14.3 = 6,28.3 = 18,84
12. L. Bangun = s.s - 1/2prkuadrat
100 - (1/2.3,14.5.5) = 100 - 39,25
= 60,75
13. L. Bangun = prkuadrat - 1/4prkuadrat
=22/7 x 28 x 28 - 1/4 x 22/7 x 28 x 28
= 2464 - 616 = 1848

Maaf kalau salah
