To start, squares are a shape in which all of its sides are congruent to one another. Knowing the length of one side would mean that you would know the length of all the other sides.
Because you know that one side measures 22 cm, you can conclude that all the other sides of the square are also at a length/width of 22 cm.
Next, you will find the area of the square.
Because the area formula is Area=Length * Width, you can easily find the area of the square by multiplying 22*22 since the length and width of any square is the same.
When you simplify 22*22, you should get 484.
Therefore, the area of the square canvas would be 484 cm squared.
