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,
