Are the shapes labelled congruent? please explain what congruent is and how i can find if shapes are congruent

Yes they are. Explanation provided below.

Step-by-step explanation:

Two shapes are congruent when they are the same shape and size. Its obvious that both are rectangles and if we look at the grid, we can see that both rectangles are 2 by 4. Since they both have the same shape and size, they are in fact congruent.

Best of Luck!

47 - 90 = 43

43 - 180 = x

x = 137
