Perimeter of rectangle = 2 ( l + b) units ,
area of rectangle = lb sq . units 
180                    = l x 12 
l = 180 /12 
l = 15 m 
perimeter of rectangle = 2 ( 15 + 12 ) 
                                 = 2 ( 27) 
                                 = 54 m

So breadth of rectangle = 12 m
so let the length be l
so area = length x breadth = 180
                         12 x b = 180
                               b = 15 m

so perimeter = 2(l + b) = 2(15 + 12) = 54 m ANSWER
