Answer: 2(l+b) = 200 meters
2(40+x+x) =200
80 + 4x =200
4x= 200-80
Therefore x=120/4= 30 meters
length of the plot =40+30=70 meters per side

Perimeter of a rectangular plot = 200m
Let its breadth be b
its length be (40+b)
ATP
2(l+b) = 200
= 2(40+b+b) = 200
= 80+4b = 200
= 4b = 200-80
= b = 120/4
= b = 30
Ans: Length = (40+30)m = 70m
