The general formula for a triangle is Base x Height / 2. That applies quite easily for a right angle triangle.
The given dimensions are not compliant for the construction of a right angle triangle but the area of any triangle is: 0.5*base*height
It depends where the X is.If you want the end across from the right angle, check out this answer.How_do_you_find_the_hypotenuse_in_a_right_triangle
First find the area of the square (length x width) then find the area of the triangle (base x height x 2) and add the two answers together.Quadrilateral just means "four sides", but the sides have to be straight.Assuming it's a right-angle triangle? Such a triangle is half of a rectangle or square, so times by 2).
(base x height) / 2
That depends on what x is: a leg, an angle, what?
you go get a calculator

Cut it exactly down the middle, along its height, and put one piece aside. The remaining side is a right triangle. The slanting side of the right triangle is a whole side of the original equilateral triangle, the bottom is half of an original side, and the vertical line is the height of the original triangle. Now you have a right triangle and you know the lengths of two of its sides, so you use what you know about right triangles to find the length of the third side, which is the height of the original equilateral triangle. It turns out to be 0.866 times the side of the equilateral triangle. (rounded) Technically, that's (1/2) x (side) x sqrt(3)

180-x-y (x and y are the sides you already know) there are 180 degrees in a triangle. The remaining # is the last angle
A right angle triangle has a 90 degree angle with two acute angles and the 3 interior angles add up to 180 degrees
right
drop a line from the vertex to the bottom line of the triangle you get a right angle triangle with side 6, 3 and x where x is the altitude of the triangle 6^2=3^2+x^2 use pythagoreus theorem 36=9+x^2 x=sqrt 27=3sqrt3=5.196cm
