Answer:
Step-by-step explanation:
I don't think you can. Let's think of a triangle, and a horizontal line with a certain length.
The height is a certain length, but the thing is that the height can be anywhere on the triangle, and the area would still be the same. For example we could have this triangle with area 30 units squared:
_
_ _
_ _ _
Base = 10 units, Height = 6 units
And we can have this triangle with area 30 units squared too:
___
___ ___
___ ___
Bae =10 units, Height = 6 units
The lengths of the two sides on the top triangle are shorter than the lengths of the sides on this bottom triangle, so you cannot find the perimeter as it varies.
