    To find the perimeter and area of a rectangle with a length of 12 cm and a breadth of 8 cm, we can use the following formulas:

    Perimeter of a rectangle: P = 2(length + breadth)

    Area of a rectangle: A = length × breadth

    Using these formulas, we can calculate the perimeter and area:

    Perimeter: P = 2(12 cm + 8 cm) = 2(20 cm) = 40 cm

    Area: A = 12 cm × 8 cm = 96 cm²

    Therefore, the perimeter of the rectangle is 40 cm, and the area is 96 cm².

    2. As for the quadrilateral with one pair of opposite sides parallel and equal in length, and all angles being right angles, this describes a special type of quadrilateral called a rectangle. A rectangle has two pairs of parallel sides and all four angles are right angles.
