An isosceles triangle has side lengths $8$ cm, $10$ cm and $10$ cm. The longest side of a similar triangle is $20$ cm. What is the perimeter of the larger triangle, in centimeters?

Each side of the similar triangle is twice  as long as in the orignal triangle

 

So  perimeter  = ( 16 + 20 + 20)  =  56
