tolong keliling dan luasnya..pakai cara yaa

Keliling = 12cm + 8cm + 12cm + 6cm + 10cm = 48 cm

Luas = Luas jajargenjang + Luas segitiga

Luas jajargenjang = a x t = 8 x 10 = 80 cm²
Luas segitiga = 1/2 x a x t = 1/2 x 8 x 6 = 24 cm²

Luas = 80 cm² + 24 cm² = 104 cm²

K = 12 cm + 8 cm + 12 cm + 6 cm + 10 cm
K = 48 cm

L = (8 × 10) + (1/2 × 8 × 6)
L = 80 cm^2 + 24 cm^2
L = 104 cm^2
