Jawaban:
L = 52 cm
P = 19 cm
Keliling persegi panjang = 142 cm
Luas persegi panjang = 988 cm²
Penjelasan dengan langkah-langkah:
Keliling persegi panjang
K = 2 × (p + l)
K = 2 × (19 + 52)
K = 2 × 71
K = 142 cm
Luas persegi panjang
L = p × l
L = 19 × 52
L = 988 cm²

- Penyelesaian -
K = 2(p + l)
= 2(52 + 19)
= 2(71)
= 2 × 71
= 142 cm
L = P × L
= 52 × 19
= 988 cm²
