Answer 2

Answer:   ⇒  Let the length of one side be x meters and other side be y meters. Then,

⇒  x+y+x=30        ----- ( 1 )          [ Given ]

∴   y=30−2x          ----- ( 2 )

⇒  Area of the vegetable garden =100m

2

⇒  xy=100

⇒  x(30−2x)=100              [ From ( 2 ) ]

⇒  30x−2x

2

=100

⇒  15x−x

2

=50

⇒  x

2

−15x+50=0

⇒  x

2

−10x−5x+50=0

⇒  (x−10)(x−5)=0

⇒  x=5,10

When x=5, we have

⇒  y=30−2×5=20

When x=10, we have

⇒  y=30−2×10=10
