Jawaban:
Rumus luas persegi = sisi × sisi
Rumus keliling persegi = 4 × sisi
d. 36 m²
36 m² = s × s
36 m² = 6 × 6
Panjang sisi = 6 cm
Keliling = 4 × s = 4 × 6 = 24 cm
e. 64 dm²
64 dm² = s × s
64 dm² = 8 × 8
Panjang sisi = 8 cm
Keliling = 4 × 8 = 32 cm
f. 81 dm²
81 dm² = s × s
81 dm² = 9 × 9
Panjang sisi = 9 cm
Keliling = 4 × 9 = 36 cm
