Answer 1

5.
L = 162 cm²
KL = KN = 12 cm

L = jumlah sisi sejajar x t/2
162 = (12 + 12 + PM) x 12/2
162 = (24 + PM) x 6
24 + PM = 162/6
24 + PM = 27
PM = 3 cm


6.
AC = 36 cm
L = 432 cm²

L = 1/2 x AC x BD
432 = 1/2 x 36 x BD
432 = 18 x BD
BD = 432/18
BD = 24 cm


7.
L = jumlah sisi sejajar x t/2
L = (15 + 15 + 7 + 9) x 12/2
L = 46 x 6
L = 276 cm²
