Answer: If polygon is a square, a = 51/2 = 25.5 units
If polygon is an equilateral triangle, a = 34 units
...
Explanation:
Hello, I need more information. Is this 2 dimensional object a square, a rectangle, a triangle?
If this polygon is a square with side length a, then:
Perimeter = 4a = 102 ; a = 102/4 = 51/2 units
-----------------
If this polygon is a equilateral triangle with side length a, then:
P = 3a = 102; a = 102/3 = 34 units
