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

  1. 1st possible dimensions
    Length of rectangle=3x + 3x
    Breadth of rectangle= 2.5y+2.5y

    Check:
    Perimeter= 2(3x) + 2(2.5y)
    = (6x + 5y)cm

    2nd possible dimensions

    Length of rectangle= 2x + 1.5y
    Breadth of rectangle= 2x + 2y

    Check
    Perimeter= 2(2x + 1.5y) + (2x + 2y)
    = 4x + 3y + 2x + 2y
    = (6x + 5y)cm
