Answer:
5![\sqrt{2}](https://tex.z-dn.net/?f=%5Csqrt%7B2%7D)
Step-by-step explanation:
The geometric mean of 2 numbers a and b is
![\sqrt{ab}](https://tex.z-dn.net/?f=%5Csqrt%7Bab%7D)
Hence
The geometric mean of 5 and 10 is
![\sqrt{5(10)}](https://tex.z-dn.net/?f=%5Csqrt%7B5%2810%29%7D)
= ![\sqrt{50}](https://tex.z-dn.net/?f=%5Csqrt%7B50%7D)
=
=
×
= 5![\sqrt{2}](https://tex.z-dn.net/?f=%5Csqrt%7B2%7D)
Answer: Use the formula A=1/2bh. A is the area, B is the base, and H is the height. It is pretty straight forward from there.
