Answer:
First, you could assume that the 3rd side (not given) is the hypotenuse of the triangle. In that case the pythagorean theorem would give you 32+42=x2 which simplifies to 9+16=x2, which again simplifies to 25=x2 or x=5, and you would have {3,4,5} as the lengths of the sides of your triangle.

d. Notice that we can write the line integral as

By Green's theorem, the line integral is equivalent to

where  is the triangle bounded by
 is the triangle bounded by  , and this integral is simply twice the area of
, and this integral is simply twice the area of  .
.  is a right triangle with legs 2 and 5, so its area is 5 and the integral's value is 10.
