tolong dong bantu saya untuk menjawab soal soal mengenai luas bangun datar gabungan , kalo bisa jawab pake jalannya , dan jawab 1 - 6 , please jawab dengan bena

1.) L.1 = 1/2× a × t
= 1/2 × 18cm × 23cm
= 1/2 × 414 cm = 207cm²
L.2 = p×l
= 57cm × 28cm = 1596cm²
––————+
1803cm²

2.) L.1 = p×l
= 58cm × 32cm = 1856cm²
L.2 = 1/2×a×t
= 1/2×25cm×18cm
= 1/2×450cm = 225cm²
——————+
2081cm²

3.) L.1 = p×l
= 50cm×41cm = 2050cm²
L.2 = p×l
= 28cm×16cm = 448cm²
——————+
2498cm²

4.) L = a×t×2
= 65cm×31cm×2
= 2205cm² × 2 = 4410cm
*dikali 2, karena terdapat 2 bangun jajargenjang yang sama panjang.

5.) L.1 = p×l
= 30cm×20cm = 600cm²
L.2 = 1/2×( a+b )×t
= 1/2×(20cm+5cm)×18cm
= 1/2×25cm×18cm
= 1/2× 450cm. = 225cm²
————+
= 825cm²

6.) L.1 = s×s
= 36cm×36cm = 1296cm²
L.2 = 1/2×a×t
= 1/2×64cm×24cm
= 1/2×1536cm = 768cm²
———––+
2064cm²


semoga bermanfaat ya!
