A) \[256c{{m}^{2}}\]
B) \[96\sqrt{3}c{{m}^{2}}\]
C) \[\frac{66}{\sqrt{3}}c{{m}^{2}}\]
D) \[\frac{256}{\sqrt{3}}c{{m}^{2}}\]
Correct Answer: D
Solution :
(d): \[{{a}^{2}}-\frac{{{a}^{2}}}{4}={{16}^{2}}\] \[=\frac{3{{a}^{2}}}{4}=256\] \[{{a}^{2}}=\frac{1024}{3}\] Area \[=\frac{1}{2}\times a\times 16=\frac{1}{2}\times \frac{32}{\sqrt{3}}\times 16=\frac{256}{\sqrt{3}}\]You need to login to perform this action.
