Answer:

60 m, 61 m

Explanation:

If "a" and "b" represent the lengths of the sides adjacent to the right angle, the area is ...

area = (1/2)ab

Filling in the given information, we can find the other side to be ...

330 m² = (1/2)(11 m)b

60 m = b . . . . . . divide by the coefficient of b

Then the remaining side can be found from the Pythagorean theorem:

c² = a² + b² = 11² + 60² = 3721

c = √3721 = 61 . . . meters

The lengths of the other two sides are 60 m and 61 m.
