The size of a rectangular triangle is increased in such a way that the slanting side increases at 2cm/s, while one of the other sides increases at 3cm/s. Determine the tempo at which the third side of the triangle changes when r = 5cm and y = 3cm.

Hey buddy, it shouldnt be rectangular triangle, it has to be right angular triangle so the whole scenario brings it to a triangle with one degree as 90 use Pythagorean theorem and solve the problem.
When slant side is 5cm and one side is 3 cm, the other side would be sqrt (5^2-3^2) = 4cm.
but the later part of the question is wrong here. it should be that the slanting side increases at 3cm / s and the other side increase at 2 cm/s.. to maintain the triangular shape..
Check out the problem once again

Triangles aren't rectangles. There are no rectangular triangles. If you meant a right triangle, then say so.
You did not define r and y. You did not specify if the triangle stays a right triangle even when the sides are increasing in length.
Define the problem better, and someone will find a solution.
