How many triangles are there with circumference of 23cm and side length of integer By the way, how to do the following

First determine the length of the longest side, then list and calculate. Take this problem as an example: the longest side is 11, 11,6,6; 11,7,5; 11,8,4; 11,9,3; 11,10,2; 11,11,1. A total of 6, 10,7,6; 10,8,5; 10,9,4; 10,10,3. A total of 4, 9, 9,7; 9,8,6; 9,9,5. A total of 3

If the perimeter of the triangle is 10, and a = B + C-3, B = C + 1.5, then what are a and B equal to

a=3.5 b=4 c=2.5

Find all sides are integers, and the perimeter value is equal to twice the area value of the triangle

Let the lengths of three sides be a, B and C respectively, then the square of triangle area = (a + B + C) (- A + B + C) (a-b + C) (a + B-C) / 16. From the condition, we get 4 (a + B + C) = (- A + B + C) (a-b + C) (a + B-C). Let x = - A + B + C, y = A-B + C, z = a + B-C, then x, y, Z are positive integers of the same odd and even, and X + y +
