Answer:

The Perimeter of an equilateral triangle = 1.4x+2+1.4x+2+1.4x+2

                                                                  = 4.2x+6

The Perimeter of a regular hexagon = 0.5x+2+0.5x+2+0.5x+2+0.5x+2+0.5x+2+0.5x+2

= 3x+12

Given that the perimeters are equal

4.2x+6 = 3x+12

4.2x - 3x = 12-6

1.2x = 6

x = 6/1.2

x=5

The side length of the triangle = 1.4x+2

                                                   = 1.4 (5) +2

                                                   = 9 inches

The side length of hexagon = 0.5x+2

                                              = 0.5(5) +2

                                              = 4.5inches
