A) 2a
B) \[\frac{a}{\sqrt{2}}\]
C) \[{{a}^{2}}/2\]
D) \[{{a}^{2}}/4\]
Correct Answer: C
Solution :
\[\text{Side}=\frac{\text{Diagonal}}{\sqrt{2}}=\frac{a}{\sqrt{2}}\] \[\therefore \] \[\text{Area=(Side}{{\text{)}}^{\text{2}}}\] \[={{\left( \frac{a}{\sqrt{2}} \right)}^{2}}\,sq\,cm\] \[=\frac{{{a}^{2}}}{2}\,sq\,cm\]You need to login to perform this action.
