Answer:

51.25

Base = 2.5^2 = 6.25

Triangles = \frac{9 * 2.5 * 4}{2}

9 * 2.5 * 2 = 45

45 + 6.25 = 51.25

ABC will undergo two transformations to give abc. Which pair of transformations will give a different image of abc if the order
ExtremeBDS [4]
You can consider the triangle (as on in the picture) and apply to it composition of two transformations:
1. reflection about the line y=x to form ΔA'B'C' and translation 1 unit right and 5 units up to form ΔA''B''C'';
2. translation 1 unit right and 5 units up to form ΔA'B'C' and reflection about the line y=x to form ΔA''B''C''.
You can see that results are different.

On added picture blue colour responds to composition of transformations 1 and red colour to composition of transformations 2.
