What is the area of this polygon?

43.5 units²

45.5 units²

46.5 units²

49.5 units²

43.5 unit^2.

Step-by-step explanation:

WE can split this into 3 triangles and 1 rectangle.

Area = 1/2 * 3*2 + 1/2 * 5 * 1 + 1/2*3*4 + 4*8

=  3 + 2.5 + 6 + 32

= 43.5 sq units.

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3
