The area of a rectangle is 12 square cm. The diagonal of the rectangle is 5 cm. What is the perimeter (in cm) of the rectangle?
Answer
The correct answer is D: 14. With area l×b = 12 and diagonal √(l²+b²) = 5, we get l²+b² = 25. Then (l+b)² = 25 + 2×12 = 49, so l+b = 7.
- A.16

- D.14✓ Correct
With area l×b = 12 and diagonal √(l²+b²) = 5, we get l²+b² = 25. Then (l+b)² = 25 + 2×12 = 49, so l+b = 7. Perimeter = 2×7 = 14 cm.
