Laura is making two art pieces that are both in the shape of triangles. She wants to glue a decorative border around the triangles.

How much border would she need for the ​triangle DFG ​ ?

3 / 6 = 18 / DG

1 /2 =18 / DG          cross multiply

DG = 2 x 18

DG = 36 inches

Perimeter of DFG =18 + 24 + 36 = 78 inches - the border of triangle DFG.
