How to do this? I confused lol.

31 cm²

Step-by-step explanation:

First find the are of the triangle, then subtract the are of the square

Area triangle = 1/2b * h

Area triangle = 1/2(14*5)

Area triangle = 1/2(70)

Area triangle = 35

Now the area of the square

Area square = 2 * 2

Area square = 4

Now subtract

Area shaded = 35 - 4

Area shaded = 31

If my answer is incorrect, pls correct me!

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
