There is only one basic shape for an equilateral triangle. The area can only vary as the length of the sides vary.
It is possible depending on what type of triangle it is. For instance if it was an equilateral triangle then all sides would be equal and then by means of Pythagoras' theorem you could work out the height of the triangle and using the formula: 1/2*base*height = area
add the sides toghther and then you'll have your perimeter of your triangle
A triangle can have only three sides. No triangle can have 9 sides!
56 cm2 * * * * * Only if these are the shorter legs of a right angled triangle and there is no justification for making that assumption. Two sides of a triangle are not sufficient to determine its area.
It is not possible to answer the question with only the lengths of two sides of a triangle.

No.

you can't
when trying to find the angle of a right triangle using only the opposite leg and the hypotenuse, eg. angle =sin opp leg over hyp * * * * * Also to find the area of a triangle if two sides and the included angle are known. Or the area of a sector of a circle.
A triangle by definition only has 2 dimensions.
With great difficulty - it is impossible without further information.For example:A triangle with sides 3, 4, 5 - base 3, height 4 has area 6 units2;a triangle with sides 2, 6, ~6.32 (√40) - base 2 height 6 has area 6 units2.Both the triangles have the same area but different sides; those are both right angled triangles, but other ones are possible, eg a triangle with sides 2.5, ~4.92 (1/2 x √97), 6 also has base 6 and height 2 and an area 6 units2.
If you only have the triangle's area, then you only know the product of (base times height) ... it's double the area ... but you can't tell what either of those individual lengths is.
