Answer:
P = 60 cm
Step-by-step explanation:
To solve this question we will use the property of the tangents drawn from a point to a circle.
"Length of tangents drawn from a point to a circle are equal in measure."
By this property,
Therefore, BG ≅ FB ≅ 7.5 cm
AG ≅ AH ≅ 6.5 cm
CF ≅ EC ≅ 8.5 cm
Since m∠B ≅ m∠D
Therefore, length of tangents FB ≅ GB ≅ DE ≅ DH ≅ 7.5 cm
Since, Perimeter of ABCD = AB + BC + CD + DA
AB = 7.5 + 6.5 = 14 cm
BC = 7.5 + 8.5 = 16 cm
CD = 8.5 + 7.5 = 16 cm
DA = 7.5 + 6.5 = 14 cm
Now Perimeter = 16 + 16 + 14 + 14 = 60 cm
Therefore, P = 60 cm will be the answer.
