7. luas trapesium = jumlah sisi sejajar . t / 2 = 48 cm + 12 cm . 24 m / 2 = 60 cm . 1.200 cm / 2 =72.000 cm²
60 x 1200
72.000cm²
8. l = d1 x d2 / 2
120 cm ² = 15 cm x d2 : 2
d2 = 120cm² x 2 : 15
d2 = 16 CM
9. L = S²
729 = s²
s = √729
s = 27
10. 420 = 28 x t
t = 420 : 28
= 15cm
= 48 cm + 12 cm . 24 m / 2
= 60 cm . 1.200 cm / 2
=72.000 cm²
8. luas belah ketupat = d1 . d2 / 2
120 = 15 . d2 / 2
d2 = 120 / 15 . 2
d2 = 16 cm
9. luas persegi = s²
729 = s²
s = √ 729
s = 27 cm
10. luas jajargenjang = a . t
420 = 28 . t
t = 420 / 28
t = 15 cm
