= 1/2 * ( 14 + 8 ) * 4
= 1/2 * 24 * 4
= 48 cm2
Luas Segitiga = 1/2 * a * t
= 1/2 * 8 * 7
= 28 cm2
1/2 × alas × tinggi = 1/2 × 8 × 7 = 28 cm²
trapesium
1/2 × (d1 + d2) × tinggi = 1/2 × (8 + 14) × 4 = 1/2 × (22) × 4 = 44 cm²
segitiga + trapesium = 28 + 44 = 72 cm²
21.) persegi
sisi × sisi = 14 × 14 = 196 dm²
lingkaran
π × r² = π × 7 × 7 = 22/7 × 7 × 7 = 154 dm²
persegi + lingkaran = 196 + 154 = 350 dm²
