MERITNATION PLEASE GIVE ALL FORMULAE FOR PERIMETER AND AREA OF RECTILINEAR FIGURES

 Perimeter of a regular polygon = Number of sides × Length of one side
 Perimeter of a square = 4 × (Side)
 Perimeter of a rectangle = 2 (Length + Breadth)

 Area of a square = (Side)²
 Area of a rectangle = (Length × Breadth)

 Area of a parallelogram = Base × Height

 Area of a triangle = ½ × Base × Height
 The circumference of a circle = π × Diameter = 2π × Radius

 Area of a circle = π × (Radius)²
