Dear Student,

Since AB,BC and AC are tangents to incircle
Hence the line drawn from centre O to tangents at point of contact would be 90Hence Lets say OL⊥ABArea of △OAB=12×r×ABsimilarly Area of △OAC=12×r×ACand Area of △OCB=12×r×CBHence area of △ABC=Area of △OAB+Area of △OAC+Area of △OBC⇒12×r(AB+BC+AC)=12×3×(AB+BC+AC)But since the image is not clear, it is difficult to proceed with this question

Kindly repost the question with a clear image
