The diagonal of a square equals 2–√
times the side length. Using 1.4 for the square root of 2, what is the approximate length in feet from one corner to an opposite corner of a square park that is 70 feet on a side?(1 point)
ft.
times the side length. Using 1.4 for the square root of 2, what is the approximate length in feet from one corner to an opposite corner of a square park that is 70 feet on a side?(1 point)
ft.
To find the approximate length from one corner to an opposite corner of a square park, we can use the formula for the diagonal of a square:
diagonal = sqrt(2) * side length.
Given that the side length is 70 feet, we can substitute this value into the formula:
diagonal = 1.4 * 70.
Calculating this expression gives us:
diagonal = 98 feet.
Therefore, the approximate length from one corner to an opposite corner of the square park is 98 feet.
diagonal = sqrt(2) * side length.
