Example 3

easy
Find the perimeter of a square with side length 99 m.

Solution

  1. 1
    A square has four equal sides, so P=4sP = 4s.
  2. 2
    Substitute: P=4(9)=36P = 4(9) = 36 m.

Answer

P=36 mP = 36 \text{ m}
A square is a special rectangle where all four sides are equal, simplifying the perimeter formula to P=4sP = 4s.
