= 6 cm
c = 10 cm
a² + b² = c²
a² = c² - b²
a² = 10² - 6²
a² = 100 - 36
a² = 64
√a² = √64
a = 8
t trapesium = a
= 8 cm
Ka = Jumlah seluruh sisi
= 8 cm + 7 cm + 10 cm + 13 cm
= 38 cm
La = 1/2 × (a + b) × t
= 1/2 × (7 + 13) × 8
= 1/2 × 20 × 8
= 10 × 8
= 80 cm²
V = La × t
1600 = 80 × t
1600 = 80t
20 = t
LP = 2(La) + (Ka × t)
= 2(80) + (38 × 20)
= 160 + 760
= 920 cm²
