The perimeter of the triangle is 40 inches. If you wanted to construct a similar triangle with a perimeter of 50 inches, what would be the length of the shortest side of the triangle?

Consider a triangle with a right angle, and one "acute" angle very close to 90 degrees. That means the other acute angle is near "zero" degrees, and the shortest side is almost zero.
Your question cannot be answered. 
the shortest side of the new triangle would be 50/40 or 1.25 times as long as the shortest side of the original triangle.
(perimeter is a linear measurement, so perimeter is directly proportional to the length of sides of similar polygons)
