Q. |
Jay started cycling along the boundaries of a square field from corner point $A$. After half an hour he reached the corner point $C$, diagonally opposite to $A$. If his speed was 8 km/hr, the area of the filed in square km is: |

✖ A. |
64 |

✖ B. |
16 |

✖ C. |
9 |

✔ D. |
4 |

**Solution:**

Option(**D**) is correct

Distance covered by Jay in \(\dfrac{1}{2}\) hr = 4 km

Therefore, side of the square = \(\dfrac{4}{2}=2\) km

Hence, Area = $2×2$ = **4** square km
