If it is an equilateral triangle with 3 equal sides of 4cm then its perimeter is 12cm
52 + 122 = 25 + 144 = 169 = 132 This calculation confirms that the three sides of length 5, 12 and 13 cm form a right angled triangle with the side of length 13cm being the hypotenuse.
It will be a right angle triangle with a base of 3cm, a height of 4cm and a hypotenuse of 5cm
30 sq cm ((12 x 5)/2)

If a right triangle has sides of 16Cm and 12Cm, the hypotenuse is: 20 cm
If two sides of a triangle have lengths of 5cm and 12cm, then the third side can have any length that's more than 7cm and less than 17cm. If the third side is 13cm, then the triangle is a right triangle.
Isosceles
If it is an equilateral triangle with 3 equal sides of 4cm then its perimeter is 12cm
22cm
No
I cut out the lengths to have a visual look at the problem and the answer is NO you cannot arrange 5cm, 12cm, and 19cm into a triangle. Even straightening out the lengths of 5cm and 12cm into a 180 degree angle will not measure out to the 19cm. You cannot have a side that is more than the length of the other two sides combined in a triangle.
It depends on the length of the third side.
