A) \[1,080\,{{m}^{2}}\]
B) \[640\,{{m}^{2}}\]
C) \[1,620\,{{m}^{2}}\]
D) \[2,160\,{{m}^{2}}\]
Correct Answer: A
Solution :
Let breadth = b m Then, length \[=\frac{6}{5}bm\] \[\because \] Perimeter = 132 \[\therefore \] \[2\left( b+\frac{6}{5}b \right)=132\Rightarrow \,b=30\,m\] Hence, length \[=\frac{6}{5}\times 30\,=36\,m\] And area = length \[\times \] breadth \[=36\times 30=1080\,{{m}^{2}}\].
