Let's fill up the table below:

i. Length = Breadth = 3 – x m


Area = Length Breadth


Area =


Area =


Area of the rectangular land =


ii. Length = Breadth = 5x + 2 m


Area = Length Breadth


Area =


Area =


Area of the rectangular land =


iii. Area = Breadth = 4x m


Area = Length Breadth


Length =


Length =


Length of the rectangular land = m


iv. Area = Length = m


Area = Length Breadth


Breadth =


Breadth =


Breadth of the rectangular land = m


v. Length = Breadth = 2 – 5x m


Area = Length Breadth


Area =


Area =


Area of the rectangular land =


vi. Area = Breadth = (4 + 10p) m


Area = Length Breadth


Length =



Length = (-10p + 4) m


Length of the rectangular land = (-10p + 4) m


vii. Area = Length = (11m - 13n) m


Area = Length Breadth


Breadth =



Breadth = 11m + 13n


Breadth of the rectangular land = (11m + 13n) m


viii. Length = 9x - y Breadth = 9x + y m


Area = Length Breadth


Area = (9x - y) × (9x + y )


Area =


Area of the rectangular land =
