Perimeter of an Isosceles Triangle

To find the perimeter of an isosceles triangle, we need to know the lengths of the two equal sides and the length of the base. In this case, the given isosceles triangle has sides measuring 12 cm and 25 cm.

Let's calculate the perimeter step by step:

1. The length of the base is equal to one of the equal sides, which is 12 cm. 2. The other two sides are also equal and measure 25 cm each.

To find the perimeter, we add up the lengths of all three sides:

Perimeter = 12 cm + 25 cm + 25 cm

Now, let's calculate the perimeter:

Perimeter = 12 cm + 25 cm + 25 cm = 62 cm

Therefore, the perimeter of the given isosceles triangle is 62 cm.
