- 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.
- 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.
