Penjelasan dengan langkah-langkah:
A. panjang dua garis sejajar = 7+19
= 26cm
B. tinggi trapesium = 8cm
C. Keliling
kaki trapesium = √((½(19-7))²+8²)
kaki trapesium = √((36)+(64))
kaki trapesium = 10cm
keliling = 2 × kaki trapesium + jumlah sisi sejajar
keliling = 2 × 10 + 7 + 19
keliling = 46cm
D. panjang kaki trapesium
