If you know the length of one side of a square, you can work out the perimeter of the whole square . explain how.

Squares are equal on all 4 sides, so one side = the other sides. Squares are congruent

For a square to be well a square it has to have 4 equal sides or it wont be a square. There are four sides on a square and if youknow one of the sides then all the others will be the same and you can add them all up
