there is 7 hexagons in the design
Thirteen separte hexagons have 13x6 sides, or 78 sides. However, it's possible that they have shared borders, so then there would be fewer because you wouldn't count the same side twice if it was shared.
All triangles will tessellate. All quadrilaterals will tessellate.There are 15 classes of irregular convex pentagons (the latest discovered in 2015) which will tessellate.Regular hexagons will tessellate. In addition, there are 3 classes of irregular convex hexagons which will tessellate.No convex polygon with 7 or more sides will tessellate.There are many concave polygonal shapes as well as non-polygonal shapes which will tessellate. For example of the latter, look for MC Escher's symmetric artwork on the web.

Oh, dude, let me break it down for you. So, a trapezoid has 4 sides while a hexagon has 6 sides. To form a hexagon, you need 3 trapezoids because if you try to fit 4 trapezoids together, you're just gonna end up with a wonky shape that's not a hexagon. So, it takes 3 trapezoids to make 4 hexagons. Easy peasy!

None. Though there can be ten if the hexagons are concave hexagons.
It is extremely difficult to determine.All triangles and quadrilaterals will tessellate.There are 15 classes of irregular convex pentagons which will tessellate.Regular hexagons and three classes of irregular convex hexagons will tessellate.In addition there are several examples of concave polygons, particularly those with an even number of sides, which will tessellate.Finally, there are very many non-polygonal shapes, some derived from polygons, which will also tessellate. For examples of this last class of shapes, search the web for MC Escher's Symmetry artwork.
