Materi : Bangun Ruang Sisi Datar
Lp Bangun diatas
Lp = 2( pt + lt ) + a × t + ( a + 2s ) × tp
Lp = 2( 150.72 + 72.72 ) + 72.48 + ( 72 + 120 ) × 150
Lp = 2( 10.800 + 5.184 ) + 3.456 + 192 × 150
Lp = 2( 15.984 cm² ) + 3.456 cm² + 28.800 cm²
Lp = 31.968 cm² + 32.256 cm²
{ Lp = 64.224 cm² }
Semoga bisa membantu
