If it is an equilateral, for example if one side was 3 then you times the 3 by 3 because there are 3 equal sides. However, if it's not an equilateral you have to add them all up.

Assuming you mean perimeter (not pirimeter) and triangle (traingle) you need to sum together the lengths of the three sides.
Use Pythagoras' theorem to find the hypotenuse which works out as 25cm Perimeter = 25+24+7 = 56cm
The perimeter of a triangle is the sum of its 3 sides.
I am assuming that "traingle" is meant to be triangle and "permeter" is meant to be perimeter.The area of a triangle cannot be equal to its perimeter because the area is a measure in 2-dimensional space whereas a perimeter is a 1-dimensional measure. So their dimensions will always be different.Furthermore, the area of a triangle is not determined by its perimeter. The area of a triangle can be changed - without affecting its perimeter - simply by changing the angles.
Yes, but it would have to be a triangle, not traingle!
