Diketahui : - Luas Persegi Panjang (L) = 10 2/5 cm² - Lebar (l) = 3 1/4 cm
Ditanya : - Panjang (p) = ......?
Penyelesaian : - Panjang (p) : L = p × l p = L ÷ l p = 10 2/5 cm² ÷ 3 1/4 cm p = 52/5 cm² ÷ 13/4 cm p = 52/5 cm × 4/13 p = 4/5 cm × 4/1 p = 16/5 cm p = 3 1/5 cm

Diketahui :
- Luas Persegi Panjang (L) = 10 2/5 cm²
- Lebar (l) = 3 1/4 cm
Ditanya :
- Panjang (p) = ......?
Penyelesaian :
- Panjang (p) :
L = p × l
p = L ÷ l
p = 10 2/5 cm² ÷ 3 1/4 cm
p = 52/5 cm² ÷ 13/4 cm
p = 52/5 cm × 4/13
p = 4/5 cm × 4/1
p = 16/5 cm
p = 3 1/5 cm
