Open in App

Solution

Given
Each side of isosceles triangle $= 13 c m$
Third side of isosceles triangle $= 10 c m$
Hence, the perimeter of isosceles triangle can be calculated as follows :
Perimeter $=$ sum of all sides
$= 13 + 13 + 10$
We get,
$= 36 c m$
Therefore, the perimeter of isosceles triangle $= 36 c m$
