Answer:
16 cm^2 and 49 cm^2
Step-by-step explanation:
The ratio of areas is the square of the ratio of linear dimensions, so is ...
(4/7)^2 = 16/49
The sum of these "ratio units" is 16 +49 = 65. The sum of triangle areas is 65 cm^2, so each "ratio unit" must stand for 1 cm^2 of area. That is, the triangles must have areas of ...

Answer:
3/5*8/9=8/15; A
Explanation:
First, you want to multiply both of the numerators together. 3*8=24.
Then, you want to multiply both of the denominators together. 5*9=45.
If you put the numerator and the denominator together, it comes out to be 24/45.
Lastly, you want to simplify 24/45. Divide those both by 3, and you get 8/15.
Hope that helps!
