If that's all you know about it, then you can't figure out the area. There are an infinite
number of different isosceles triangles that all have a 5-cm side but different areas.
You need to know more about it than just the length of one side.
0.5 x side a x side b where a and b are any side except the longest one (the hypotenuse)
Turn the triangle into a square work out the area for that then half your answer ---- For an equilateral triangle, use the formula 1/2 x base x perpendicular height to work out the area.
I think you need at least one other piece of information. A length of a side? An angle? Is it a right angled triangle?
The area of any triangle has the same formula, which is base times height, divided by 2. A scalene triangle is a triangle with three sides of unequal length, which is not important when calculating the area.
its called a scalene triangle, scalene triangles have 3 different sides to work out area you do base x Perpendicular height divided by 2 the problem is i dont know which side is base of which is hight, to work out the area of a triangle. you have given little information which is not helpful

you just have to measure it in inches all the sidesAnother Answer:-Area of a triangle = 0.5*base*height
The way you can work out the length of a triangle is if you are given the height and the area of that triangle ( this works of you don't want to measure it) or you could just measure it.

Use a ruler and measure one side only. All sides will measure the same if the triangle is equilateral.
Using Pythagoras' theorem the height of the equilateral triangle works out as about 7 cm and so with the given dimensions it would appear to be quite difficult to work out the lateral area.
the base of the triangle multiplied by height, then that number divided by 2. A = b*h/2
Base x height divided by 2
