Step-by-step explanation:

let

l=x

b=y

according to question

2(x+y)=82

=x+y=41...........eqn(1)

according to question xy=400

=x=400/y

putting the value of x in eqn(1)

we get

400/y+y=41

=(y^2+400)/y=41

=y^2+400=41y

=y^2-41y+400=0

=y^2-25y-16y+400=0

=y(y-25)-16(y-25)=0

=(y-16)(y-25)=0

=y=16 or 25

answer is 16 or 25
