Q. The perimeter of a square painting is 12 feet. How long is each side of the painting?_____ feet
Identify Side Length: Let s be the side length of the square. The perimeter of a square is calculated by adding up all four sides, which are equal. So, the formula for the perimeter of a square is P=4s.
Substitute Perimeter: Given the perimeter of the square painting is 12 feet. Substitute 12 for P in the formula P=4s. 12=4s.
Solve for Side Length: Solve for s by dividing both sides of the equation by 4. 412=s. 3=s.
