Algebra... Different "Faces" of Algebra (II)

The perimeter of a rectangle is (6x + 5y) cm.
Suggest 2 possible dimensions of the rectangle.

e.g.
Length of rectangle = 2x + 2y cm
Breadth of rectangle = x + 0.5y cm
Check:
Perimeter = 2 (2x + 2y) + 2 (x + 0.5y) cm
= 4x + 4y + 2x + y cm
= 6x + 5y cm

  3. 1)
    Length=(3x+1.5y)cm
    Breadth=1y cm
    Total=(6x+5y) cm
    2)
    Length=(2x+2.5y)cm
    Breadth=1x cm
    Total=(6x+5y)cm

  6. There are many possibilities.One is : Length: 3x
    Breadth: 2.5y

  7. length: 2.5x cm
    breadth: 0.5x + 2.5y cm

    Perimeter= (2.5x cm)+(2.5x cm)+(0.5+2.5y cm)+(0.5+2.5y cm)
    = ( 6x + 5y ) cm

  8. Length-(1x+2y) cm
    Breadth-(2x+0.5y) cm
    Check- 2(1x+2y) cm + 2(2x+0.5) cm = (6x+5y) cm

  11. length: (3x+0.5y)
    breath: (2y)cm
    Check: 2(3x+0.5y)cm + (2y)cm=(6x+5y)

  12. length-(2x+y)cm
    breadth-(x+1.5y)cm
    total-2(2x+y)cm+2(x+1.5)cm=(6x+5y)cm

  13. length = 1.5x cm
    breadth = 1.25y cm

  14. 1)Length : (1.5x + 1.25y)
    1)Breadth : (1.5x + 1.25y)
    1) Perimeter : 1.5x + 1.5x + 1.5x +1.5x + 1.25y + 1.25y + 1.25y + 1.25y = 6x + 5y

    2)Length : (3x)
    2)Breadth : (2.5y)
    2)Perimeter : 3x +3x + 2.5y +2.5y = 6x + 5y

    (6x + 5y)
