The centroid of a\[\Delta ABC\]is G. The area of \[\Delta ABC\] is \[60\text{ }c{{m}^{2}}.\]The area of \[\Delta GBC\] is |
A) \[40\,c{{m}^{2}}\]
B) \[20\,c{{m}^{2}}\]
C) \[30\,c{{m}^{2}}\]
D) \[10\,c{{m}^{2}}\]
Correct Answer: B
Solution :
Area of \[\Delta ABC=60c{{m}^{2}}\] |
\[\because \] \[AG:GE=2:1\] |
\[\therefore \] Area of \[\Delta GBC=\frac{1}{3}\times 60\] |
\[=20\,c{{m}^{2}}\] |
