Answer 2

52) BC = BD-CD
= 6 3/4 - 3 1/8
= 6 6/8 - 3 1/8
= 3 5/8 cm

AB = AD-BC-CD
= 12 4/5 - 3 5/8 - 3 1/8 ---> KPK penyebut = 40
= 12 32/40 - 3 25/40 - 3 5/40
= 6 2/40
= 6 1/20 cm

53) voli = 1 - 1/4 - 3/8 ----> KPK penyebut = 8
= 8/8 - 2/8- 3/8
= 3/8
jadi, 3/8 . 40 = 15 orang


55) a.p sbnrnya = 32 cm . 150 = 4800 cm = 48 m
b. l sbnrnya = 15 cm .150 = 2250 cm = 22,5 m
c. L sbnrnya = p.l
= 48.22,5 = 1080 m²
