Solution

The correct option is C 20 cm
The given triangle is an isosceles triangle.
So, length of the third side would be either 5 cm or 12 cm.
But, the third side can’t be 5 cm, as the sum of two sides
(5 cm + 5 cm = 10 cm) is not greater than the third side which is 20 cm.
Hence, the length of the third side will be 20 cm.
