Penjelasan dengan langkah-langkah:
k = s1 + s2 + s3 + s4
k = 6 + 4 + 12 + 10
k = 10 cm + 22 cm
k = 32 cm
__
cari dlu tingginya
= sisi alas - sisi atas
= 12 - 4
= 8 cm
tingginya
= √10² - 8²
= √100 - 64
= √36
= 6 cm
nah, luasnya
L = 1/2 × ( jlh sisi sejajar ) × t
L = 1/2 × (12 + 4) × 6
L = 1/2 × 16 × 6
L = 8 × 6
L = 48 cm²
___________________________________________
K Trapesium = S1 + S2 + S3 + S4
K Trapesium = 6 + 12 + 10 + 4
K Trapesium = 6 + 12 + 14
K Trapesium = 6 + 26
K Trapesium = 32 cm
___________________________________________ L Trapesium = ½ × (S Sejajar) × t
L Trapesium = ½ × (4 + 12) × 6
L Trapesium = ½ × 16 × 6
L Trapesium = ½ × 96
L Trapesium = 48 cm²
