Question

solve the following question

Answer 1

7. Let the dimensions be 4x and 5x.
   Let the rope's length be the perimeter of the rectangle
   So, perimeter of rectangle= 2(length+ breadth)
   360 m= 2(4x+ 5x)
              = 2*9x
              = 18x
          x  = 360/18
              = 20

Length = 5x
             = 5*20
             = 100 m
Breadth= 4x
              = 4*20
              = 80 m
