Relationships of 2D Figures Geometry

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

• perimeter

• area

• volume

Area is the the total space taken up by a flat (2-D) surface or shape of an object.

• Area

• perimeter

• volume

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

• A = s x s, where s is side length

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

• P = 4s, where s is side length

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

Put these polygons in order of their shape hierarchy

• Parallelogram

• Quadrilateral

• Rectangle

• Square

a ​ (a)   is a line segment that forms the boundary of a two-dimensional figure.

• congruency marks

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

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

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