Answer:
0.43
Step-by-step explanation:
2+3+1+1=7
7*4+28==Area of full shape
(2*4)+(1*4)=12==Area of shaded shapes
12/28=0.428571>rounded up>0.43
7.28 is the answer sorry if i’m wrong
12 because if u multiply 3*4 it is 12 and 4*3 is 12 so they both have 12 in common I hope this helps and have a nice day =)
