answer = 50.2
The formula after making h the subject of formula is: ![h=\frac{5d^2}{4}](https://tex.z-dn.net/?f=h%3D%5Cfrac%7B5d%5E2%7D%7B4%7D)
Further explanation:
Given formula is:
![d=\sqrt{\frac{4h}{5}}\\](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B%5Cfrac%7B4h%7D%7B5%7D%7D%5C%5C)
Making any variable subject of any formula means that the concerned variable should be isolated on one side of the formula. Which means it will be a dependent quantity.
So,
First of all we have to take the h out of the square root
So,
![Taking\ square\ on\ both\ sides\\(d)^2=(\sqrt{\frac{4h}{5}})^2\\d^2=\frac{4h}{5}\\Multiplying\ both\ sides\ by\ 5\\5d^2=\frac{4h}{5}*5\\5d^2=4h\\Dividing\ both\ sides\ by\ 4\\\frac{5d^2}{4}=\frac{4h}{4}\\h=\frac{5d^2}{4}](https://tex.z-dn.net/?f=Taking%5C%20square%5C%20on%5C%20both%5C%20sides%5C%5C%28d%29%5E2%3D%28%5Csqrt%7B%5Cfrac%7B4h%7D%7B5%7D%7D%29%5E2%5C%5Cd%5E2%3D%5Cfrac%7B4h%7D%7B5%7D%5C%5CMultiplying%5C%20both%5C%20sides%5C%20by%5C%205%5C%5C5d%5E2%3D%5Cfrac%7B4h%7D%7B5%7D%2A5%5C%5C5d%5E2%3D4h%5C%5CDividing%5C%20both%5C%20sides%5C%20by%5C%204%5C%5C%5Cfrac%7B5d%5E2%7D%7B4%7D%3D%5Cfrac%7B4h%7D%7B4%7D%5C%5Ch%3D%5Cfrac%7B5d%5E2%7D%7B4%7D)
So,
The formula after making h the subject of formula is: ![h=\frac{5d^2}{4}](https://tex.z-dn.net/?f=h%3D%5Cfrac%7B5d%5E2%7D%7B4%7D)
