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.
Use a ruler and measure one side only. All sides will measure the same if the triangle is equilateral.

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.
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
the base of the triangle multiplied by height, then that number divided by 2. A = b*h/2
Base x height divided by 2
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.
