A dodecagon has 12 sides, and a quadrilateral has 4. So in 2 dodecagons and 4 quadrilaterals there are 2*12 + 4*4 = 24 + 16 = 40 sides altogether.
A heptagon has seven sides and a quadrilateral has four, so 1 heptagon and 3 quadrilaterals have 1*7 + 3*4 = 7 + 12 = 19 sides altogether.
A dodecagon has 12 sides.
