A nonagon has nine sides, and a triangle has three, so altogether they have 12 sides.
A pentagon has fives sides, and a quadrilateral has four. So 2 pentagons and 1 quadrilateral have 2*5 + 4 = 10 + 4 = 14 sides altogether.
A quadrilateral has four sides, and a hexagon has six. So one quadrilateral and three hexagons have 1*4 + 3*6 sides = 4 + 18 sides = 22 sides.
A nonagon has nine sides and a pentagon has five sides. So 4 nonagons and 1 pentagon have 4*9 + 1*5 sides = 41 sides
