Question

ABC B-90 AC - 29 cm and AB - 21 cm, then the semiperimeter of ABC




​

Answer 1

Answer:

total In geometry, the semiperimeter of a polygon is half its perimeter. Although it has such a simple derivation from the perimeter, the semiperimeter appears frequently enough in formulas for triangles and other figures that it is given a separate name. When the semiperimeter occurs as part of a formula, it is typically denoted by the letter s.

Step-by-step explanation:

In any triangle, the distance around the boundary of the triangle from a vertex to the point on the opposite edge touched by an excircle equals the semiperimeter.
