Understanding Squares: Side Length, Perimeter, and Area

The video tutorial explains how to determine the side length, perimeter, and area of a square using grid paper. It begins by identifying the side length of the square as six centimeters. The perimeter is calculated by adding the lengths of all sides, resulting in 24 centimeters, and is also explained using the formula P = 4s. The area is determined by counting the square centimeters within the square, totaling 36 square centimeters, and is also explained using the formula A = s^2. The tutorial concludes with a summary of these calculations.

What is the side length of the square on the grid paper?

• 7 cm

• 6 cm
