L = 1.152 cm²

Penjelasan dengan langkah-langkah:

cari sisi miring segituga dulu, misal r

r² = 12² + 16²

= 144 + 256

= 400

r = √400 = 20 cm

L = 2x L.alas + L.selimut

= 2x(1/2 x 16 x 12) + (16+12+20)x20

= 192 + 48x20

= 192 + 960

= 1.152 cm²

Luas permukaan = (2 x luas alas) + (keliling alas x tinggi) = luas alas =1/2 alas x tinggi =20 x 12 =240/2=120 keliling = s+s+s =16+12+20 =48

=(2x120) + (48x20) =240 + 960 = 1200cm
