DEFINATION OF AREA  Area (mathematics), in mathematics,

the size of an enclosed region, given in terms of the square of a designated unit of length. Formulas for the areas of simple geometric figures include a2 for a square, where a is a side; ab for a rectangle, where a and b are two adjacent sides.

AREA OF RECTANGLE

AREA OF RECTANGLE = LENGTH * BREADTH

EXAMPLE OF AREA OF RECTANGLE IN RECTANGLE ABCD 6CM

LENGTH= 6 C.M BREADTH =3 C.M AREA = L*B = 6 C.M*3 C.M AREA = 18 C.M

3 CM

DEFINATION OF PERIMETER OF RECTANGLE Perimeter, or boundary, the line drawn around the edge of an area or shape. For example, the perimeter of a rectangle is the sum of its four sides.

PERIMETER OF RECTANGLE

PERIMETER OF RECTANGLE = 2 * (LENGTH * BREADTH)

EXAMPLE OF PERIMETER OF RECTANGLE IN RECTANGLE ABCD LENGTH= 6 C.M BREADTH =3 C.M PERIMETER = 2 * (L+B) = 2 * (6 C.M+3 C.M) PERIMETER = 18 C.M
