Jawaban:
A. 360 cm
B. 5600 cm ²
Penjelasan dengan langkah-langkah:
A. K = BG + GF + AF + EA + DE + DC + CI + IH + BH
= 30 + 30 + 30 + 40 + 40 + 40 + 50 + 50 + 50
= 90 + 120 + 150
= 360 cm
B. L = L persegi bawah + L persegi kiri + L persegi kanan + L segitiga siku-siku
= 30 × 30 + 40 × 40 + 50 × 50 + (40×30)/2
= 900 + 1600 + 2500 + 1200/2
= 2500 + 2500 + 600
= 5600 cm²
