Lp. Balok = 2 x ( ( p x l ) + ( p x t ) + ( l + t ) ) = 2 x ( ( 6 x 6 ) + ( 6 x 12 ) + ( 6 x 12 ) ) = 2 x ( ( 36 ) + ( 72 ) + ( 72 ) ) = 2 x ( ( 180 ) ) = 360 Phytagoras --> SM = SM = + SM = + SM = = 5 Lp. 4 segitiga = 1/2 x a x t x 4 = 1/2 x 6 x 5 x 4 = 3 x 5 x 4 = 15 x 4 = 60 cm Semua Lp. = Lp. balok + Lp. 4 segitiga = 360 + 60 = 420
= 2 x ( ( 6 x 6 ) + ( 6 x 12 ) + ( 6 x 12 ) )
