Question

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

Answer 1

Step-by-step explanation:

2 ×2×pie× r = 800

4 pie r= 800

pie r = 200

22/7 r = 200

22/7 r^2 = 200 r

Area = pie r^2

= 200 r

Answer 2

Mensuration

The park is of square shape.

Tanisk walks around the park twice and walked 800 m.

Hence the perimeter of park $= \frac{800}{2}=400\ m$

Perimeter of square $= 400\ m$

Hence , we can find the side of square park ,

$4 \times \ side=perimeter= 400\ m\\\\\implies side=\frac{400}{4} \\\\\implies side=100\ m$

So, the area of square $= side^2= 100^2=10000 \ m^2$

Hence, the required area of square park is 10000 m².
