The perimeter of any polygon is calculated by adding the lengths of all the sides.

24. Since a rectangle has two pairs of congruent sides, two sides will have a length L, and the other two sides will have a length W, for a perimeter
or
In this case and -->

25. An equilateral triangle has three congruent sides, so if the length of each side is S, the perimeter, P, is

If the length of each side is , the perimeter is
--> -->

26.
a. If we presume that the perimeters of the rectangle in problem 24 and the triangle in problem 25 are equal,
--> --> --> --> --> -->
b.Substituting , the perimeter for the rectangle is
--> --> -->
Substituting , the perimeter for the triangle is
