**MathMate**, Monday, October 10, 2011 at 8:59am"...of a right triangle" is a trigger to the use of Pythagoras theorem to find the third side given the lengths of two legs.

So the length of the third side, S, is:

S=sqrt(9^2+40^2)

which should come out as an integer.

Adding the lengths of all three sides will give the required perimeter.

The are of the triangle is the product of the two legs divided by two.
