K = 8 + 4 + 4 = 16 cm
L = ½ . 8 . 0 = 0 cm² [ Teorama Phytagoras tidak dapat berlaku ]
K = 8 + 17 + 20 = 45 cm
L = ½ . 8 . 17 = 4 . 17 = 68 cm²
K = 15 cm + b + c [ sisi lain tidak bisa diketahui ]
L = ½ . 15 cm . 8 cm = 60 cm²
K = 12 + 17 + 21 = 50 cm
L = ½ . 12 . 17 = 6 . 17 = 102 cm²
K = 7 + 9 + 11 = 27 cm
L = ½ . 11 . 6 = 33 cm²
K = 12 + 12 + 12 = 36 cm
L = ½ . 12 . 6√3 = 36√3 cm²
Semoga bisa membantu

1. K.segitiga = s+s+s L.segitiga = a x t : 2
= 4+4+8 = 8 x 4 : 2
= 16 cm = 16 cm²
2. K.segitiga = s+s+s L.segitiga = a x t : 2
= 8+20+17 = 17 x 8 : 2
= 45 cm = 68 cm²
3. K.segitiga = s+s+s L.segitiga = a x t : 2
= 17+8+15 = 15 x 8 : 2
= 40 cm = 60 cm²
4. K.segitiga = s+s+s L.segitiga = a x t : 2
= 17+21+12 = 12 x 17 : 2
= 50 cm = 102 cm²
5. K.segitiga = s+s+s L.segitiga = a x t : 2
= 7+9+11 = 11 x 6 : 2
= 27 cm = 33 cm²
6. K.segitiga = s+s+s L.segitiga = a x t : 2
= 12+12+12 = 12 x 12 : 2
= 36 cm = 72 cm²
