84. JAWABAN TERCERDAS MENANTI. JAWAB PAKAI CARA YG BAIK DAN MUDAH DIMENGERTI THX

Answer 1

9. L segitiga = ½ x a x t
= ½ x 14 cm x 12 cm
= 7 x 12
= 84 cm²

L 4 segitiga= 4 x 84 cm = 336 cm²

L persegi= s² = 14² = 196cm²
L permukaan = 336 cm² + 196 cm²= 532 cm²

Answer 2

9LP = (s . s) + 4(a . t)/2
= (14 . 14) + 4 (14 . 12)/2
=196 + 336
=532cm²


10)LP =2πr (r+t)
= 2 . 22/7 . 14 .(14 +24)
=88 . 38
=3344cm²
