Answer 1

For the triangles, it would be 102 because each of the triangles contribute 1 unit except the ones on the ends which give 2.
For the squares it's 202 with the same logic as above but each square contributes 2 units.
As for hexagons it's 402. If you see the pattern it's just n(s-2)+2 where n is the number of shapes and s is the number of sides on the shape so for n hexagons, it's 4n +2.
