tolong di jawab dengan cara kerjanya ya

1) L1 = p × l
= 20 × 10
= 200 cm²
L2 = s²
= 10 × 10
= 100 cm²
Lttl = L1 + L2
= 200 + 100
= 300 cm²

2) L1 = p × l
= 15 × 10
= 150 cm²
L2 = ½ × a × t
= ½ × 10 × 8
= 40 cm²
Lttl = L1 + L2
= 150 + 40
= 190 cm²

3) L1 = ½ × a × t
= ½ × 14 × 12
= 84 cm²
L2 = p × l
= 25 × 14
= 350 cm²
L3 = ½ × π × r²
= ½ × 22/7 × 7 × 7
= 77 cm²
Lttl = L1 + L2 + L3
= 84 + 350 + 77
= 511 cm²

4) L1 = ½ × a × t
= ½ × 20 × 14
= 140 cm²
L2 = ½ × π × r²
= ½ × 22/7 × 7 × 7
= 77 cm²
Lttl = L1 + L2
= 140 + 77
= 217 cm²

5) L1 = s²
= 15 × 15
= 225 cm²
L2 = ½ × a × t
= ½ × 15 × 15
= 112,5 cm²
Lttl = L1 + L2
= 225 + 112,5
= 337,5 cm²
