Jawaban:
L=120 cm²
K=44 cm
Penjelasan dengan langkah-langkah:
L=Lsegitiga 1+Lsegitiga 2+Lpersegi panjang
L=(a×t×1/2)+(a×t×1/2)+(p×l)
L=(8×3×1/2)+(8×3×1/2)+(12×8)
L=(12)+(12)+(96)
L=120
K=5+5+12+5+5+12
semoga membantu :)
buat jadi tercerdas yaa
Jawab:
K = 70 cm
L = 120 cm^2
Keliling :
A. s + s + s = 5 cm + 5 cm + 5 cm = 15 cm
B. 2 x ( p + l ) = 2 x ( 12 cm + 8 cm ) = 2 x 20 cm = 40 cm
C. s + s + s = 5 cm + 5 cm + 5 cm = 15 cm
KG = A + B + C = 15 cm + 40 cm + 15 cm = 70 cm
Luas :
A. a x t : 2 = 8 cm x 3 cm : 2 = 12 cm^2
B. p x l = 12 cm x 8 cm = 96 cm^2
C. a x t : 2 = 8 cm x 3 cm : 2 = 12 cm^2
LG = A + B + C = 12 cm^2 + 96 cm^2 + 12 cm^2 = 120 cm^2
Semoga bermanfaat :)
Jadikan jawaban terbaik ya :)
