Verified answer
L1 = L 1/2 segitiga sama kakiL2 = L 1/2 lingkaran
L1 = 1/4 × a × t
L1 = 1/4 × 6 × 7
L1 = 10,5 m^2
L2 = 1/2 × phi × r × r
L2 = 1/2 × 3,14 × 3 × 3
L2 = 14,13 m^2
Jadi luas yang tidak diarsir adalah 10,5 + 14,13 m^2 = 24,63 m^2

Jawabannyaluas segitiga=a×t:2
=7×6:2
=21 m2
21:2=10,5 m2
luas setengah lingkaran
1/2×phi×r2
=1/2×3,14×3×3
=14,13 m2
luas yg tdk diarsir:
luas setengah lingkaran+luas setengah segitiga
=14,13+10,5 m2
=26,43 m2
