You can  put this solution on YOUR website! If the ratio of the corresponding sides of two similar triangles are 4:9,and the sides of the smaller triangle are 10cm,16cm, and 18cm, what would be the perimeter of the larger triangle? 
--------------- 
Multiply each of the smaller triangle sides by (9/4) 
You get (9/4)10= 20 5/4 cm 
(9/4)16=36 cm 
(9/4)18=81/2= 40 1/2 cm 
Cheers,
