= jml sisi sejajar × t ÷ 2
= (10 + 25) × 12 ÷ 2
= 35 × 6
= 210 cm2
b. L 1/2 lingkaran + L segitiga
= ( 1/2 × 22/7 × 14 × 14) + ( 14×10 ÷ 2)
= 308 + 70
= 378 cm2
c. L 1/2 lingkaran + L persegi panj + L segitiga
= (1/2 × 22/7 × 14 × 14) + (28×8) + ( 14×10 ÷ 2)
= 308 + 224 + 70
= 602 cm2
d. L 1/2 lingkaran + L trapesium
= ( 1/2 × 3,14 × 10 × 10) + ( 26+14 × 20 ÷ 2)
= 157 + 400
557 cm2
