Ртреугольника=аbс=19*22*21=62

Answer 2

Perimeter Calculation

To find the perimeter of a triangle with sides of 19, 22, and 21 centimeters, you simply add the lengths of all three sides together.

The perimeter (P) of a triangle is given by the formula: P = side1 + side2 + side3

Substituting the given side lengths: P = 19 + 22 + 21

Calculation

P = 19 + 22 + 21 = 62

So, the perimeter of the triangle with sides of 19, 22, and 21 centimeters is 62 centimeters.
