A) \[100\sqrt{3}\]\[c{{m}^{2}}\]
B) \[8\sqrt{3}\]\[c{{m}^{2}}\]
C) \[160\sqrt{3}\]\[c{{m}^{2}}\]
D) 100 \[c{{m}^{2}}\]
Correct Answer: B
Solution :
(b): \[Side=\frac{16}{4}=4cm\] but, \[AB=AD=4\]cm \[\angle DAB=\angle DCB={{60}^{{}^\circ }}\] \[\therefore \]Area of the rhombus \[=2\times \frac{\sqrt{3}}{4}\times {{(4)}^{2}}\] \[=2\times \frac{\sqrt{3}}{4}\times 4\times 4=8\sqrt{3}\,c{{m}^{2}}\]You need to login to perform this action.
