Answer: 2.5 in
Step-by-step explanation:
From the question, we are informed that Mary reduced the size of a painting to a width of 3.3 in even though the original width was 42.9 in wide. This shows that the size of the painting was 3.3/42.9 = 1/13
Therefore, the height of it was originally 32.5 in will be:
= 1/13 × 32.5
= 2.5 in
Therefore, the height is 2.5 in.
