Minified Lua

Copy
Rect={area=0,length=0,breadth=0}function Rect:new(o,length,breadth)o=o or{}setmetatable(o,self)self.__index=self self.length=length or 0 self.breadth=breadth or 0 self.area=length*breadth;return o end function Rect:printRect()print("The calculated Area of Rect:  ",self.area)end

Beautified Lua

Copy
Rect = {
	area = 0,
	length = 0,
	breadth = 0
}
function Rect:new(o, length, breadth)
	o = o or {}
	setmetatable(o, self)
	self.__index = self
	self.length = length or 0
	self.breadth = breadth or 0
	self.area = length * breadth;
