Verified answer
MAPEL = MATEMATIKABAB BANGUN DATAR
diketahui =
tinggi segitiga(1) = 15cm
alas segitiga(2) = 8cm
sisi miring trapesium = 5cm
tinggi trapesium = 4cm
ditanya = kll bangun??
alas trapesium = √15² + 8²
alas trapesium = √225 + 64
alas trapesium = √289
alas trapesium = 17cm
alas segitiga pada trapesium
= √5² - 4²
= √25 - 16
= √9
= 3cm
panjang salah satu sisi sejajar trapesium
= 17cm - 3cm - 3cm
= 17 - 6cm
= 11cm
kll bangun = jumlah semua sisi
= 15cm + 5cm + 11cm + 5cm + 8cm
= 44cm
semoga membantu
