PA and PB are tangents from P to a circle with centre O and radius 6 cm, and PA = 8 cm. Find the perimeter of quadrilateral OAPB.

Class 10Tangent Lengths and IncirclesGeometry
  • A20 cm
  • B28 cm
  • C14 cm
  • D48 cm

Step-by-Step Solution

OA = OB = 6 cm (radii) and PA = PB = 8 cm (equal tangents). Perimeter = 6 + 8 + 8 + 6 = 28 cm. 14 cm counts each length only once.
Answer: B) 28 cm
