5) L = 1/2 x alas x tinggi 30 = 1/2 x alas x 12 30 = 6 x alas alas = 30/6 = 5 cm
sisi miring = √12² + 5² =√144 +25 =√169 = 13 cm
6). garis miring = √6 ²+8² = √36 + 64 = √100 = 10 cm luas segitiga 1 = 1/2 x 8 x 6 = 24 cm² luas segitiga 2 = 1/2 x 10 x 10 = 50 cm² luas total = 24 + 50 = 74 cm²
semoga membantu
no 7 ketinggalan ma af 7) alas = (64 - (13 x 2)) / 2 = (64 - 26) / 2 = 38 : 2 = 19 cm
L = a x t = 19 x 12 = 228 cm²

Brillian075. L = 1/2 x a x t 30 = 1/2 x a x 12 a = 30 x 2 : 12 = 5 cm
sisi miring = √ 5² + 12² = √ 25 + 144 = √ 169 = 13 cm ( a)
6. L1 = 1/2 x a x t = 1/2 x 6 x 8 = 24 cm
sisi miring = √ 6² + 8² = √ 36 + 64 = √ 100 = 10 cm
L2 = 1/2 x a x t = 1/2 x 10 x 10 = 50 cm
L bangun datar = 24 + 50 = 74 cm(b)
7. a = 64 - (13 x 2) : 2 = 64 - 26 : 2 = 38 : 2 = 19 cm
30 = 1/2 x alas x 12
30 = 6 x alas
alas = 30/6 = 5 cm
sisi miring = √12² + 5²
=√144 +25
=√169 = 13 cm
6). garis miring = √6 ²+8²
= √36 + 64
= √100 = 10 cm
luas segitiga 1 = 1/2 x 8 x 6
= 24 cm²
luas segitiga 2 = 1/2 x 10 x 10
= 50 cm²
luas total = 24 + 50 = 74 cm²

7) alas = (64 - (13 x 2)) / 2
= (64 - 26) / 2
= 38 : 2 = 19 cm
L = a x t
= 19 x 12
= 228 cm²
30 = 1/2 x a x 12
a = 30 x 2 : 12
= 5 cm
sisi miring = √ 5² + 12²
= √ 25 + 144
= √ 169 = 13 cm ( a)
6. L1 = 1/2 x a x t
= 1/2 x 6 x 8
= 24 cm
sisi miring = √ 6² + 8²
= √ 36 + 64
= √ 100 = 10 cm
L2 = 1/2 x a x t
= 1/2 x 10 x 10
= 50 cm
L bangun datar = 24 + 50 = 74 cm (b)
7. a = 64 - (13 x 2) : 2
= 64 - 26 : 2
= 38 : 2 = 19 cm
L = a x t
= 19 x 12
= 228 cm (c)
