​ (a)   is a linear measurement of the distance around the outer edge of a figure.

• perimeter

• area

• volume

The formula to find the perimeter of a square is ​ (a)  

• P = 4s, where s is side length

• P = 2 l + 2w, where l is length and w is width

• A = s x s, where s is side length

• A = l x w, where l is length and w is width
