They could all be the same length, or two of them could be the same, or they
could all be different. In any case, when you add them all up, the number you
get is called the "perimeter" of the triangle.

scalene has 3 different length sides.
You spell ' equaiateral;, correct;y as 'equilateral'. A SCALENE triangle cannot be EQUILATERAL, because for all scalene triangles , the length of the three sides are all different and the angles are all different values. An EQUILATERAL triangles has its three sides of equal length , and its three angles all at 60 degrees.
If the two adjacent sides of a triangle are 3' and 4', the hypotenuse is: 5'
I Am pretty sure it's a triangle(: No it's not a triangle has 3 sides i think its a trapezoid.
An equilateral triangle has all three sides the same length. → perimeter = 3 × 10.5 = 31.5 units.
