Question 897054: A scalene triangle has one side 5cm longer than the shortest side and another side 10cm longer than the shortest side. A square has all four of its sides the same length as the shortest side of the triangle. If the perimeter of the square is the same as the perimeter of the triangle, find the length of each side of the triangle.

Triangle: shortest side is x.
Sides of the triangle are x, x+5, x+10.

Square: side is x.

Perimeter of square is 4x.
Given also 4x=x%2B%28x%2B5%29%2B%28x%2B10%29, perimeter of square equals perimeter of triangle.

Solve for x and then determine x+5 and x+10.
