I'll do the math for this, it may take me a few minutes so i will update this comment with an answer in just a minute. I always get anxious when nobody replies kind of quickly as i feel it is being forgotten. So just a heads up i'm working on a answer!
If you need the sum than here is an equation for it 7x3= 21
Since the area of a square is side squared, you can find the length of each side by finding the square root of the area, which is 5. Since there are four sides in a circle, just multiple 5 by 4 and your answer is 20 units.
Divide 24 from both sides
Since one kilometer is equal to about 0.621 miles, a runner travels 3.105 miles in a five-kilometer race.
