Answer 1

Answer:

5040 Rs

Step-by-step explanation:

let the length and breadth of a rectangle field be 4x and 3x respectively

Area of rectangle=1728m^2

                     L×B=1728

               4x × 3x=1728

                      12x=1728

                       x=1728/12

                       x=12

L = 4x = 4 × 12 = 48m

B = 3x = 3 × 12 = 36m

Perimeter = 2 ( L × B )

                 = 2 ( 48 + 36 )

                 = 2 ×84

                 =  168m

Cost = 168 × 30 = 5040 Rs
