To find the approximate length from one corner to an opposite corner of a square park, we can use the formula given: diagonal = (2–√) * side length.
Given information:
Square side length = 70 feet
Approximate square root of 2 = 1.4
First, we can substitute the values into the formula:
diagonal = (2–√) * side length
diagonal = (2–1.4) * 70
Next, simplify the equation:
diagonal = (0.6) * 70
Finally, calculate the diagonal length:
diagonal = 42 feet
Therefore, the approximate length from one corner to an opposite corner of the square park is 42 feet.
