A) \[\text{19}000\text{ }{{\text{m}}^{\text{2}}}\]
B) \[\text{18225 }{{\text{m}}^{\text{2}}}\]
C) \[\text{17256 }{{\text{m}}^{\text{2}}}\]
D) \[\text{18325 }{{\text{m}}^{\text{2}}}\]
Correct Answer: B
Solution :
| [b] Hypotenuse \[=270m\] |
| \[Hypotenus{{e}^{2}}=Sid{{e}^{2}}+Sid{{e}^{2}}=2{{(Side)}^{2}}\] |
| \[{{(Side)}^{2}}={{(270)}^{2}}/2=72900/2=36450\] |
| or Side \[=190.91\,m\] |
| Required Area |
| \[=1/2\times 190.91\times 190.91=36446.6/2\] |
| \[=18225\,{{m}^{2}}\,\,(approx)\] |
