Answer:
A
Step-by-step explanation:
calculate the ratios AB/DE BC/EF AND AC/DF。their ratios are 1/2
the first because the ratio is always from a small to a large triangle, and it is right, the second is wrong, the sides are not congruent, the third is also wrong, the last ratio is wrong
i'd say with the given info it will be the same
16, think of 4 plus 4 plus 4 plus 4.
42
