Question

The perimeter of an isosceles triangle is $32cm$ while its equal sides together measure $18cm$. Find the third side and each of the equal sides.

Answer 1

Let the third side be $x$.

According to the question,

$Perimeter=Sumofallthreesides=x+2a$

Therefore,

$x+2a=32$

$x+18=32$

$x=14cm$

So,

The third side $=14cm$

And each equal side $=\frac{18}{2}=9cm$

Hence, this is the answer.
