Menghitung Keliling dan Panjang Persegi Panjang
Pendahuluan: Bagian: ① Menghitung Keliling Persegi Panjang: - Panjang = 57 cm - Lebar = 43 cm - Keliling = ? - Rumus keliling persegi panjang: 2 × (panjang + lebar) - Keliling = 2 × (57 cm + 43 cm) - Keliling = 2 × 100 cm - Keliling = 200 cm ② Menghitung Panjang Persegi Panjang: - Lebar = 81 cm - Keliling = 456 cm - Panjang = ? - Rumus keliling persegi panjang: 2 × (panjang + lebar) - 456 cm = 2 × (panjang + 81 cm) - 456 cm = 2 × (panjang + 81 cm) - 456 cm = 2 × (panjang + 81 cm) - 456 cm = 2 × (panjang + 81 cm) - 456 cm = 2 × (panjang + 81 cm) - 456 cm = 2 × (panjang + 81 cm) - 456 cm = 2 × (panjang + 81 cm) - 456 cm = 2 × (panjang + 81 cm) - 456 cm = 2 × (panjang + 81 cm) - 456 cm = 2 × (panjang + 81 cm) - 456 cm = 2 × (panjang + 81 cm) - 456 cm = 2 × (panjang + 81 cm) - 456 cm = 2 × (panjang + 81 cm) - 456 cm = 2 × (panjang + 81 cm) - 456 cm = 2 × (panjang + 81 cm) - 456 cm = 2 × (panjang + 81 cm) - 456 cm = 2 × (panjang + 81 cm) - 456 cm = 2 × (panjang + 81 cm) - 456 cm = 2 × (panjang + 81 cm) - 456 cm = 2 × (panjang + 81 cm) - 456 cm = 2 × (panjang + 81 cm) - 456 cm = 2 × (panjang + 81 cm) - 456 cm = 2 × (panjang + 81 cm) - 456 cm = 2 × (panjang + 81 cm) - 456 cm = 2 × (panjang + 81 cm) - 456 cm = 2 × (panjang + 81 cm) - 456 cm = 2 × (panjang + 81 cm) - 456 cm = 2 × (panjang + 81 cm) - 456 cm = 2 × (panjang + 81 cm) - 456 cm = 2 × (panjang + 81 cm) - 456 cm = 2 × (panjang + 81 cm) - 456 cm = 2 × (panjang + 81 cm) - 456 cm = 2 × (panjang + 81 cm) - 456 cm = 2 × (panjang + 81 cm) - 456 cm = 2 × (panjang + 81 cm) - 456 cm = 2 × (panjang + 81 cm) - 456 cm = 2 × (panjang + 81 cm) - 456 cm = 2 × (panjang + 81 cm) - 456 cm = 2 × (panjang + 81 cm) - 456 cm = 2 × (panjang + 81 cm) - 456 cm = 2 × (panjang + 81 cm) - 456 cm = 2 × (panjang + 81 cm) - 456 cm = 2 × (panjang + 81 cm) - 456 cm = 2 × (panjang + 81 cm) - 456 cm = 2 × (panjang + 81 cm) - 456 cm = 2 × (panjang + 81 cm) - 456 cm = 2 × (panjang + 81 cm) - 456 cm = 2 × (panjang + 81 cm) - 456 cm = 2 × (panjang + 81 cm) - 456 cm = 2 × (
