Solution

Given, distance covered in one around = 800 m

$∵$ Distance covered in one round = Perimeter of square park

$\Rightarrow$ 800 = 4 $\times$ side [ $∵$ perimeter=4 $\times$ side]

$\Rightarrow$ $\frac{800}{4} = \frac{4 \times s i d e}{4}$ [dividing both sides by 4]

$\Rightarrow$ Side = 200 m

Now, area of square = Side $\times$ Side

= 200 $\times$ 200

= 40000 sq m
