Parmindar walks around a square park once and covers 800 m. What will be the area of this park?

Answer:

Given, distance covered in one around = 800 m \[\because \] Distance covered in one round = perimeter of square park \[\Rightarrow \] \[800=4\times \,side\]                                                                                                                    [\[\because \] perimeter \[=4\times side\]] \[\Rightarrow \]         \[side=\frac{800}{4}\]                                                                                                                                  \[\Rightarrow \]          \[side=200\text{ }m\] Now, area of square \[=side\times side\] \[=200\times 200\] \[=40,000\]sq. m
