Step-by-step explanation:
The ratio height : base is ...
... 2.5 : 1.6
... = 25 : 16
... = 1.5625 : 1
You can eliminate the bogus answers B and C because ...
... B: the numbers are too close together. The larger would need to be near 13 for the smaller one to be 9.
... C: the base is larger than the height, so the ratio is less than 1, not greater than 1.

Its approximately 7.1 inches. 2 inches plus 2 inches is 4 so its obviously not a. 12.3 is just too ridiculously big for the figure so its down to C and B.
since the rounded edge is bigger than the two inches, it wouldn't be B, which leaves you with C
Hope this helped you
