The trapezoids and the irregular figures at the top left.
Step-by-step explanation:
Congruent means "in agreement or harmony." So that means in math congruent means "the same" and the trapeziods were both the same and so were the irregular figures.
The initial equation is 25x+150=650. Since she already has 150, we can subtract that from the total to get 500. We now have that 25x=500. Divide by 25 on both sides to get 20 weeks
