Perimeter of rectangle = 2(l + b)
So,
=> 200 = 2×(l + 60)
=> 200 = 2l + 120
=> 200 - 120 = 2l
=> 80 = 2l
=> 80/2 = l
=> 40 = l.
Length of rectangle is 40 m.

the perimeter of rectangle=200 m
let lenght be x m
200=2(x+60)
200/2=x+60
100=x+60
100-60=x
x=40 m
therefore the length of the rectangle is 40 m.
