Jawaban:
80 cm²
Penjelasan dengan langkah-langkah:
(1/2 × D2)² = (52/4)² - (10/2)²
(1/2 × D2)² = 13² - 5²
(1/2 × D2)² = 169 - 25
(1/2 × D2)² = 144
1/2 × D2 = √144
1/2 × D2 = 12
D2 = 12 × 2/1
D2 = 24 cm
..
Luas Belah Ketupat
= 1/2 × D1 × D2
= 1/2 × 10 × 24
= 1/2 × 240
= 120 cm²
Luas Tidak Diarsir
= Luas Belah Ketupat - Luas Arsir
= 120 - 40
= 80 cm²
