Lp = 2.la + kel. a . t lp = 2.(12.16) + (28) . 10 lp = 192 cm + 280 cm = 472 cm
semoga membantu

whongaliems = = = = = 10 cm keliling alas = 4.s = 4 . 10 = 40 cm L.permukaan = 2 x L.alas + keliling alas x t = 2 x x 12 x 16 + 40 x 10 = 192 + 400 = 592 cm²
lp = 2.(12.16) + (28) . 10
lp = 192 cm + 280 cm
= 472 cm
semoga membantu

= 10 cm
keliling alas = 4.s
= 4 . 10
= 40 cm
L.permukaan = 2 x L.alas + keliling alas x t
= 2 x x 12 x 16 + 40 x 10
= 192 + 400
= 592 cm²
