The perimeter of an isosceles triangle is 125 cm. If the base is 33 cm, find the length of the equal sides.

46 cm

The perimeter of an isosceles triangle = 125 cm

And the base = 33 cm

We know that the perimeter of a isosceles triangle =

P = (2a + b)

Where,

P = Perimeter,

a = Two equal sides,

b = Base

Let the length of the each sides be a cm

P = (2a + b)

= 125 = (2a + 33)

= (125 – 33) = 2a

= 2a = 92

= a = 46
