Jawaban:

luas prisma = 2× luas alas + keliling alas × tinggi prisma

luas alas = 2× luas trapesium

luas trapesium = (a+b)/2×t

= (7+13)/2×4

= 40 ×2 = 80 cm²

keliling alas = cari sisi miring dlu

13-7=6/2=3 cm

maka sisi miring = √3²+4²=5

maka 13+7+5+5=30

keliling alas × tinggi = 30× 10=300 cm ²

luas = 300+80=380 cm² C
