Answer
Given:
Perimeter of each regular hexagon = 30 cm
Side of each hexagon = = 5 cm
When two hexagons are joined along one side, one side of each hexagon (5 cm) coincides.
Sum of perimeters of both hexagons = 30 + 30 = 60 cm
Perimeter of new figure = 60 - 2 × 5
= 60 - 10
= 50 cm
Hence, option 4 is the correct option.
