WebStep 1: Concept and formula to be used. According to the Herons formula, Radii of excircles of a triangle can be given by r 1 = ∆ s - a r 2 = ∆ s - b r 3 = ∆ s - c Where, ∆ is the area of the triangle given by ∆ = s s - a s - b s - c. r 1, r 2, r 3 are the radii of excircles. a, b, c are the length of the sides of the triangle.
