A quadrilateral ABCD circumscribes a circle with AB = 9 cm and CD = 7 cm. What is its perimeter?

Class 10Tangent Lengths and IncirclesGeometry
  • A64 cm
  • B16 cm
  • C23 cm
  • D32 cm

Step-by-Step Solution

AB + CD = BC + AD = 16 cm, so perimeter = 16 + 16 = 32 cm. 16 cm stops after one pair of opposite sides.
Answer: D) 32 cm
