Determine how far he walked in one loop
<em>This question is incomplete, as the playground diagram and dimensions are missing. However, I'll answer on a general terms.</em>
<em></em>
What this question requires is to calculate the perimeter of the playground.
Assume that the playground is rectangular and the dimensions are: 2 meters by 3 meters.
The distance walked will be calculated using the following perimeter formula.



If it is a square with 5m as the length of one of its side, the distance would be:


<em>So basically, all you need to do is calculate the perimeter of the playground.</em>

I write it in the pic.I hope that I undrestand what you mean
Area of a cirlce=πr²
we have two radius:2r and r
area of the cirlce₁ + area of the circle₂=80 m²
area of the circle₁=π(2r)²
area of the circle₂=πr²
Then, we can suggest this quation:
π(2r)²+πr²=80
4πr²+πr²=80
π(4r²+r²)=80
π(5r²)=80
5πr²=80
r²=80/5π
r=√(80/5π)≈2.26
radius of the largest cirlce=2r=2(2.26)=4.51
Answer: the radius of the largest circle is 4.51 m
