length = width + 200m
Perimeter = 1000 (the sum of all the sides)
Perimeter = 2*W + 2* (w+ 200)
P = 2*W + 2*W + 2*200
Replacing the perimeter value
1000 = 2*W + 2*W + 2*200
1000 = 4*W + 400
4W = 1000- 400
w= 600/4
w= 150
______________________
The dimensions
width = 150 m
length = width + 200
= 150 + 200
= 350 m
________________
Answer
Width = 150 m
Length = 350 m
