A) \[400\,\,c{{m}^{2}}\]
B) \[450\,\,c{{m}^{2}}\]
C) \[375\,\,c{{m}^{2}}\]
D) \[500\,\,c{{m}^{2}}\]
Correct Answer: B
Solution :
Area of rectangle \[=l\times b=30\times 20\] \[=600\,\,c{{m}^{2}}\] Area of \[\Delta \,\,DGF\] \[=\frac{1}{2}\times b\times h\] \[=75\,c{{m}^{2}}\] Similarly area of \[\Delta \,\,AGE=75\,c{{m}^{2}}\] Area of unshaded region \[=600-(75+75)\,\,c{{m}^{2}}\] \[=450\,\,c{{m}^{2}}\]
