The area of right-angled triangle in terms of rr and r1r_1, if ∠A=90∘\angle A=90^{\circ} (where r,r1r, r_1 have their usual meanings), is
View answer and explanation
Correct option: B
rr1r r_1
Option B (rr1r r_1) is correct because the area of the right-angled triangle is equal to the product of the inradius and the exradius opposite to the right angle.
