The formula can't even be written unless you know either
-- the size of one of the other sides of the triangle, and the size
of the angles at both ends of it,
or else
-- the size of both other sides of the triangle, and the size of the
angle between them.
the formula is the Pythagorean theorem a^2+b^2=c^2
there is no specific formula for isos triangle..... 1/2bh..which means 1/2xbasexheight is the formula for all types of triangles.....so if we take isos as a triangle we can use this formula to calculate the area of the figure!
how to calculate the elbow radius or elbow length
The hypotenuse of an isosceles right triangle is 13 centimeters long. How long are its sides?
You have to use Pythagoras' Theorem to calculate the hypoteneuse.

The hypotenuse of an isosceles right triangle is 13 centimeters long. How long are its sides?
Each side of the triangle is 16.16581 units in length.
You have to use Pythagoras' Theorem to calculate the hypoteneuse.
If you want to figure out just the area of the triangle, the formula is base times height divided by 2. It does not matter if it is inside a square, as long as you have the legnths of all they sides you need to calculate the area of that triangle. If you do not, It would be very difficult.
The length of the sides of an isosceles triangle are not set in stone. An isosceles triangle is defined as a triangle with at least two congruent sides. Equilateral triangles; that is, triangles in which all sides are of equal length are also considered to be isosceles triangles. Therefore, as long as at least two sides of the triangle are congruent, (Of equal length) said triangle is an isosceles triangle.
To find the perimeter of a triangle, you need to add the lengths of all three sides. If two sides of the triangle are 6 and 5 units long, you still need to know the length of the third side to find the perimeter. Without the length of the third side, it is not possible to calculate the perimeter of the triangle.
Any length you can think of, as long as two of its sides are the same length.
An isosceles triangle has two sides of equal length.
The two equal length sides of an isosceles triangle are the legs.
