A) \[306\,{{m}^{2}}\]
B) \[307\,{{m}^{2}}\]
C) \[308\,{{m}^{2}}\]
D) \[309\,{{m}^{2}}\]
Correct Answer: A
Solution :
Draw the perpendicular CM on AB from C. From the figure, \[BM=AB-AM=40-28=12m\] Area of the field = area of rectangle AMCD + area of right angled triangle MBC \[=28\times 9+\frac{1}{2}\times 12\times 9=306\,{{m}^{2}}.\]You need to login to perform this action.
