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.
The length of the diagonal can be calculated by multiplying the side length of the square by 2–√ (or 1.4).
Diagonal length = side length * 1.4
Diagonal length = 70 ft * 1.4
Diagonal length = 98 ft
Therefore, the approximate length from one corner to an opposite corner of the square park is 98 feet.
