No.
There are with infinitely many possible dimensions for triangles with a given area.
Atlantic ocean
Divide its area by a given side
By multiplying it by a given 3rd dimension
A= 1/2(b)(h)
Area of triangle: 0.5*3*4 = 6 square feet
It depends on what equations are given.
Area of any triangle is: 0.5*base*height
You don't need to find it. From what your question states the area is already given to you.
Area of triangle: 0.5*3*4 = 6 square feet
-- If they give you the length and the area, then you don't have to look very hard to find the area. It's right there in front of you, and you only need to copy it. -- If they give you the area and one dimension, then the quotient of (area) divided by (the given dimension) is the missing dimension.
If you are only given the side lengths of a scalene triangle, it is impossible for you to find for the area, unless you are given more information... like the height of the triangle for example. If this is a right triangle you would like to find the area of, you can multiply the length of each leg with each other, and then divide that product by 2 to conclude the area of the triangle.
