Which set of numbers is always rational

Integers are always rational numbers.

The height of an equilateral triangle equals fraction square root 3/2 times the side length. Using 7/4 for the square root of 3 what is tue approximate height in meters of an equilateral triangle with a side length of 8 meters

The height (h) of an equilateral triangle can be found using the formula h = √3/2 * side length. Plugging in the given values, we have h = 7/4 * 8/2 = 14 meters. So, the approximate height of the triangle is 14 meters.

The diagonal of a square equals square root 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 700 feet on a side?

The diagonal of a square can be calculated as the square root of 2 times one side. Thus, the diagonal of a square park that is 700 feet on a side would be approximately 1.4 * 700 = 980 feet.
