The four questions are all very much alike, except for the material of the rectangular piece and the values.

Dimensions x and y.
Perimeter p is known.
x and y are related by some known factor, k.
y=kx, and either variable might be taken as width or length, depending on how the described specific problem is arranged.
Question asks for area, the value of xy.

KNOWN: p, k
UNKNOWN: x, y

Each of the four problems goes this way.

Use x to solve for y.

Finally, each of the questions asks for area, xy.
