    1. To calculate the perimeter of a rectangle, we add the lengths of all four sides. In this given question, the length is 12 cm and the breadth is 8 cm.

    Perimeter of the rectangle = 2 × (Length + Breadth)

    Perimeter = 2 × (12 cm + 8 cm)

    Perimeter = 2 × 20 cm

    Perimeter = 40 cm

    So, the perimeter of the rectangle is 40 cm.

    To find the area of a rectangle, we multiply the length by the breadth.

    Area of the rectangle = Length × Breadth

    Area = 12 cm × 8 cm

    Area = 96 cm²

    So, the area of the rectangle is 96 square cm.

    1. A quadrilateral with one pair of opposite sides parallel and equal in length, and all angles being right angles, is called a rectangle. In other words, if a quadrilateral has two pairs of opposite sides that are parallel and equal in length, it is a rectangle.
