A park in a subdivision is triangular-shaped. Two adjacent sides of the park are 581 feet and 540 feet. The angle between the sides is 83. To the nearest unit, find the area of the park in square yards. Please HELP

1- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis.2- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in the first question?
