  1. Answer:

    let length be x

    and breadth be y

    first condition.

    x-y=6

    second condition.

    2(x+y)=54

    x+y = 27

    and solve

    hope it helps you

  2. Given :-

    • Perimeter = 54 cm
    • One side = 6 cm + Other side

    To find :-

    Area of rectangle = ?

    Solution :-

    Let one side be length = x.

    So the other side be breadth = y = (x + 6) cm

    Perimeter = 2 (l + b)

    ⇒ Perimeter = 2 (x + x + 6)

    ⇒ Perimeter = 2 (2x + 6)

    ⇒ Perimeter = 4x + 12

    ⇒ 54 = 4x + 12

    ⇒ 4x = 54 – 12

    ⇒ 4x = 42

    ⇒ x = 42 ÷ 4

    x = 10.5 cm

    For finding the value of y:

    y = x + 6

    → y = 10.5 + 6

    y = 16.5 cm

    ∴ Length = 10.5 cm

    Breadth = 16.5 cm

    Area = Length × Breadth

    ⇒ Area = (10.5) (16.5)

    Area = 173.25
