For this case we have that by definition, the perimeter of a recatangle is given by:

P = 2b + 2h

Where:

b: It is the base of the rectangle

h: Is the height of the rectangle

According to the data of the statement we have:

P = 20 \ cm\\b = \frac {2} {3} h

Substituting we have:

20 = 2 \frac {2} {3} h + 2h\\20 = \frac {4} {3} h + 2h\\20 = \frac {10} {3} h\\60 = 10h\\h = \frac {60} {10}\\h = 6

Thus, the height of the rectangle is6 \ cm

b = \frac {2} {3} (6) = 4 \ cm

So the area is:

A = b * h\\A = 4 * 6\\A = 24 \ cm ^ 2

Answer:

24 \ cm ^ 2
