$$\left. \begin{array} { l } { A = \frac{690 x}{h ^ {2}} }\\ { a = x }\\ { b = a }\\ { c = b }\\ { \text{Solve for } d \text{ where} } \\ { d = c } \end{array} \right.$$

x-ৰ বাবে সমাধান কৰক

$$x=\frac{Ah^{2}}{690}$$

$$\left(c=d\text{ and }a=d\text{ and }b=d\text{ and }h=A^{-\frac{1}{2}}\sqrt{690d}\text{ and }d\neq 0\text{ and }A\neq 0\right)\text{ or }\left(c=d\text{ and }a=d\text{ and }b=d\text{ and }h=-A^{-\frac{1}{2}}\sqrt{690d}\text{ and }d\neq 0\text{ and }A\neq 0\right)\text{ or }\left(c=0\text{ and }d=0\text{ and }b=0\text{ and }h\neq 0\text{ and }a=0\text{ and }A=0\right)$$
