**drwls**, Tuesday, November 11, 2008 at 11:21amFor similar triangles, the ratio of the perimeters must be the square root of the ratio of areas, which is (in this case) sqrt(9/4) = 3/2

Therefore 4x-4 = (3/2)(2x + 6) = 3x + 9

x = 13

The perimeter of the larger triangle is therefore 4x-4 = 48 dm. That of the smaller is 2x + 6 = 32 dm
