AREA AND PERIMETER

PERIMETER (P): In geometry, perimeter can be defined as the path or the boundary that surrounds a shape. It can also be defined as the length of the outline of a shape.

EXAMPLES:

P = 6 + 4 + 2 + 3 + 8 + 7 = 30 cm

P = 12 + 2 + 3 + 8 + 5 + 4 + 4 + 6 + 5 = 49 cm

AREA: In geometry, the area can be defined as the space occupied by a flat shape or the surface of an object. The area of a figure is the number of unit squares that cover the surface of a closed figure. The area is measured in square units such as square centimeters, square feet, square inches, etc.
