The given figure is made up of two rectangles Find its total area.

A)  \[144\,\,c{{m}^{2}}\]

B)  \[216\,\,c{{m}^{2}}\]

C)  \[240\,\,c{{m}^{2}}\]

D)  \[300\,\,c{{m}^{2}}\]

Correct Answer: B

Solution :

 : Area of rectangle ABCD \[=(18\times 8)\,c{{m}^{2}}\] \[=144\text{ }c{{m}^{2}}\] Area of rectangle GEFC \[=(12\times 6)\,c{{m}^{2}}\]                                     \[=72\text{ }c{{m}^{2}}\] \[\therefore \]Total area \[=(144+72)\,\,c{{m}^{2}}=216\,c{{m}^{2}}\]
