Question

Tolong jawab nomor 5 sama 6 dong

Answer 1

Jawaban soal nomer 5
alas segitiga = 13-7
                   = 6

Lp = 2(La) + klilig alas x t
    = 2( (7 +13) x 8 : 2) + ( (10 + 13 + 7 + 8 ) x 30
    = 2 ( 80 ) + ( 38 x 30 )
    = 160 + 1140
   = 1300cm²

jawabn soal nomer 6b
Lp = 2(La ) + kliling alas x t
    = 2 ( a²/4 √3 ) + 18 x 3 x 4
    = 2 ( 18²/4 √3) + 216
   = 2 ( 324/4 √3 ) + 216
   = 2 x 81√3 + 216
   = 162√3 + 216
