Question

Tanisk walks around a square-shaped park twice and covers 800 m. What is the area of this park?

answer it with full explanation
​

Answer 1

`2 * 2 * \pi * r = 800`

`4 \pi r= 800`

`\pi r = 200`

`(22)/(7) r = 200`

`(22)/(7)r^2= 200 r`

`Area = \pi r^2`

`= 200 r`

Answer 2

the area of this park is 10000 meter²

Step-by-step explanation:

She walked two times the square shaped park twice covering 800 meters

Then one times walking the park would be 400 meters

A square has 4 similar sides, so one side shall have: 400/4 → 100 meters

If one side, length of the park is 100 meters.

Then using the square area formula: Length² → 100² → 10000 meter²
