Answer:
it is A and C
Explanation:
If you do the math and equations of all of these, you will find that:
10 is 2.5x bigger than 4 (Side lengths DE and BA)
and if we do the equation:
x · 2.5
(the x variable stands for the different side lengths of triangle ABC)
it will equal the side lengths of the bigger triangle.
and when I finished doing that, I multiplied all of the answers to find the area:
12.5 x 7.5 x 10 which altogether is 937.5
none of the other answers for the total of the triangle add up to be that, but side length EF is 7.5, which I used to get my total answer of 937.5.
So the answer is A and C
