Add them all together.
Lengths of: equal side+equal side+base = perimeter
There is only one equilateral triangle with a perimeter of 60 units. Its side lengths are integers.
For the 6:8:10 triangle, area = perimeter = 24. Also, for the 5:12:13 triangle, area = perimeter = 30. Whether these are indeed the only examples I am not sure. That would take some proving.

Semi-perimeter means half the perimeter. Calculate the perimeter, then divide that by 2 to get the semi-perimeter.
That number is called the "perimeter" of the triangle.
Lengths of: equal side+equal side+base = perimeter
Add the lengths of each side together to get the perimeter.
If the length of each side is doubled, then the perimeter is also doubled.
6+8+10=24The perimeter of the triangle is 24 inchesThe perimeter is all the side lengths added up, so that triangle would have a perimeter of 24 inches.6+8+10=24 inches
The perimeter changes and doubles as well.
Surely you know how to find the third side of a right triangle, when you know the lengths of the other two. Find it, and then add up the lengths of the three sides to get the perimeter.

A triangle has side lengths of 3, 4, and 5. The perimeter is 12 total. Perimeter is the total length of the outside of the object.
The height of a triangle alone is not enough information to find the perimeter. You need some angle measures or side lengths.
