The area of rectangular plot is 2400 square metres and its length is one one by two times to its breadth what is the perimeter

Dear Student,

Given:
length = 12×breadth
=>  breadth = 2 x length
Area of Rectangle = 2400 m2 
And we know, Area of rectangle = length x breadth
                       2400 = length x 2 x length
                      2400  = 2 x  length2 
                       24002 = length2
                         
1200 =  length2 
=>   length2 = 1200
=> length = 1200 ( on taking square root on both the sides) ​​​​
=> length = 203
then,  breadth = 2 x length

breadth = 2 x 203
breadth = 403
and we know Perimeter of rectangle = 2 (length+breadth)
                                                          = 2 (203+403)
                                                          = 2 x 60 3
                                                          = 1203 m

Regards
