Jawab:352 cm²
Penjelasan dengan langkah-langkah:
Diketahui:persegi→ sisi (s) = 8 cmdan segitigatinggi = 24-8-8 = 8→ tinggi (t) = 8 cmalas = 3×s = 3×8 = 24→ alas (a) = 24 cm
Ditanya luas gabungan4×persegi + segitiga =(4×s×s) + (a×t÷2) =(4×8×8) + (24×8÷2) =(32×8) + (24×4) =256 + 96 =352 cm²

Jawab:
352 cm²
Penjelasan dengan langkah-langkah:
Diketahui:
persegi
→ sisi (s) = 8 cm
dan segitiga
tinggi = 24-8-8 = 8
→ tinggi (t) = 8 cm
alas = 3×s = 3×8 = 24
→ alas (a) = 24 cm
Ditanya luas gabungan
4×persegi + segitiga =
(4×s×s) + (a×t÷2) =
(4×8×8) + (24×8÷2) =
(32×8) + (24×4) =
256 + 96 =
352 cm²
