Area ABD = 16*12/2
area ABC = 9*12/2
------------------------------
so the ratio of the area ABC to the area of ABD = (9*12/2)/(16*12/2) =
= 9/16

Answer: 
Step-by-step explanation:

yes, that is correct. However, you forgot another property of roots. Roots are simply exponential fractions.
![\sqrt[n]{x^m}=x^\frac{m}{n}](https://tex.z-dn.net/?f=%5Csqrt%5Bn%5D%7Bx%5Em%7D%3Dx%5E%5Cfrac%7Bm%7D%7Bn%7D)
Therefore, 
can also be rewritten as: . Notice that it cannot be -25 because that would be a negative square root which will give us an imaginary number.
