26.luas bangun datar tersebut adalah.... pakai cara yaw please....

========== Jawaban ========

Sub. Mapel = Math
Sub. Materi = Bangun Datar
Pertayaan yg diajukan = 1

Penyelesaian :
Luas trapesium
= 1/2 × (a + b) × t
= 1/2 × ((12 + 12) + 26) × 12
= (24 + 26) × 6 cm
= 50 cm × 6 cm
= 300 cm^2

Luas jajar genjang
= a × t
= 12 cm × (38 - 12)
= 12 cm × 26 cm
= 312 cm^2

Luas gabungan
= 300 cm^2 + 312 cm^2
= 612 cm^2

===========================
Hopefully is the best for you :)

Mapel : Matematika
Bab : Bangun Datar

Diketahui :
- Tinggi Bangun (tb) = 38 cm
- Tinggi Trapesium (tt) = 12 cm
- Alas Jajar Genjang (a) = 12 cm
- Sisi Atas (sa) = 24 cm
- Sisi Bawah (sb) = 26 cm

Ditanya :
- Luas Bangun (Lb) = .....?

Penyelesaian :
- Tinggi Jajar Genjang (tj) :
tj = tb - tt
tj = 38 cm - 12 cm
tj = 26 cm

- Luas Jajar Genjang (Lj) :
Lj = a × tj
Lj = 12 cm × 26 cm
Lj = 312 cm²

- Luas Trapesium (Lt) :
Lt = ½ × (sa + sb) × tt
Lt = ½ × (24 cm + 26 cm) × 12 cm
Lt = 50 cm × 6 cm
Lt = 300 cm²

- Luas Bangun (Lb) :
Lb = Lj + Lt
Lb = 312 cm² + 300 cm²
Lb = 612 cm²

Jawaban : C. 612 cm²

Maaf Kalau Salah
