Answer:
x=24
y=36
Step-by-step explanation:
x=smaller number
y=larger number
x+12=y x/2=y/3
x/2=(x+12)/3
cross multiply and distribute
3x=2x+24
x=24
24+12=y
y=36
Answer:
length x and width x-2
perimeter of rectangle=2[l+b]=2[(x-2)+x]=4x-4 is your answer
From this picture you can calculate coordinates of triangles' vertices:

.
Since
you can conclude that points A, B, C are rotated by

about the point (-0.5,0) to form points J, G, H, respectively.
Answer: A is correct choice.
