Question

Nmr 22 dan 23 terima kasih

Answer 1

22) L. alas + L. tutup = 2×( (8+5)×4/2)
= 2×(13×4/2) = 2×(52/2) = 2×26 = 52 cm^2

EF^2 = (8-5)^2 + 4^2 = 5 cm

L. EFGH = 5 × 6 = 30cm^2
L. BFGC = 5 × 6 = 30 cm^2
L. ABCD = 4 × 6 = 24 cm^2
L. EADH = 8 × 6 = 48 cm^2

Lsp = 52+30+30+24+48 = 184 cm^2

maaf, saya cuma bisa ngerjain no 22. kalo 23 sudah ketemu, nanti saya kasih tahu.
