6 square units (rounded to nearest whole number)
Explanation:
Area of triangle is found by the formula 1/2 * base * height
But we can't easily figure this out using this formula, instead we use another formula for area of a triangle:

Where
A is the area
a and b are the two side given (3 and 5 in our case)
C is the angle between a and b (53 degrees given)
We can substitute into the formula and figure out:

The area is 5.99, to the nearest whole number, the area is 6
