Answer:
Length & breadth are 40 & 50 m
Step-by-step explanation:
Let say length & breadth are L & B m respectively
Area = LB = 2000 m^2
Perimeter = 2 (L + B) = 180
L+B = 90
B = 90 - L
L (90-L) = 2000
90L - L^2 = 2000
L^2 - 90L + 2000 = 0
L^2 - 40L - 50L + 2000 = 0
(L-40)(L-50) = 0
L = 40 or 50 m
B = 90-40 or 90-50
B = 50 or 40 m
