Answers
The garden center is 50M by 20 M one side is the store 50M and the rest is 50+20+20=90 M.
You didn't say how long the store is but 50 M sounds reasonable.
w*L = 1000. (Area)
w + 2L = 90. (Fence)
w = 90 - 2L
(90 -2L)L = 1000
0 = 2L^2 - 90L + 1000
0 = L^2 - 45L + 500
L = 20 ; 25
w = 50 ; 40
20x50 and 25x40 fit the parameters
