The perimeter of a triangle is 49 cm
WebbOnce we know sides a, b, and c we can calculate the perimeter = P, the semiperimeter = s, the area = K, and the altitudes: ha, hb, and hc. Let us know if you have any other suggestions! Formulas and Calculations for a right triangle: Pythagorean Theorem for Right Triangle: a 2 + b 2 = c 2; Perimeter of Right Triangle: P = a + b + c WebbAnswer (1 of 5): A+B+C=49, B=A-3, C=2A. Now we can substitute for B and C in the first equation as follows: A+(A-3)+2A=49 so 4A-3=49 and A=13. From the second equation, B=13–3 so B=10. From the third equation, C=2(13) so C=26.
