Penjelasan dengan langkah-langkah:
panjang sisi
d1 = 16:2 = 8
d2 = 12:2 = 6
s = √8²+6²
s = √64+36
s = √100
s = 10 cm
Lp = 2 × La + (k.a × t)
Lp = 2 × (1/2.d1.d2) + ((4s) × 12)
Lp = 2 × (1/2.16.12) + (40 × 12)
Lp = 2 × (8.12) + 480
Lp = 2 × 96 + 480
Lp = 192 + 480
Lp = 672 cm²
B. 672 cm²
- Sebelum mencari luas, cari dulu sisi ketupatnya ya!
Luas permukaan
Note :
Kalau tulisannya terpotong geser aja ya^^
