Show answer & explanation
Correct answer: B
Solution: Compute perimeter and area, then form the ratio.
Perimeter = 2 × (base + adjacent side) = 2 × (12 + 7) = 38 cm.
Area = base × height = 12 × 9 = 108 cm².
Ratio of perimeter to area = 38 : 108. Simplify by dividing both terms by 2 to get 19 : 54.
Final answer: 19:54
