Answer:
given that
Perimeter = 80 m
=> 2( l + b ) =80 m
=> l + b = 40 m ---(1)
and area = 400 square m
=> l× b = 400
=> l( 80 - b) = 400
=> 80l - b square = 400
=> b square - 80l +400=0
No it's not possible. because the leanght and breadth can not defined

Answer:
Let the breadth be = x
Length = 40 - x
Area = 400 m^2
l × b = 400
(x)(40 - x) = 400
x^2 - 40x + 400 = 0
By using Identity,
(a-b)^2 = a^2 - 2ab + b^2
(x-20)^2
