To find the length of the diagonal of the square, we can use the Pythagorean Theorem. The Pythagorean Theorem states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.
In the given rectangle, the diagonal of the square represents the hypotenuse of a right triangle. The two sides of the right triangle can be determined by measuring the horizontal and vertical distances between two adjacent data points.
Considering the sides of the triangle formed by points A and B, the horizontal distance is 2 units and the vertical distance is 0 units. Plugging these values into the Pythagorean Theorem, we get:
c² = a² + b²
c² = 2² + 0²
c² = 4
Taking the square root of both sides, we get:
c = √4
c = 2
Therefore, the length of the diagonal of the square is 2 units. Rounded to the nearest hundredth, the length of the diagonal is still 2.83 units.
So, the correct answer is 2.83.
