Answer:

The area of the rectangle is 22 m^2. The perimeter of the rectangle is 19.93

Step-by-step explanation:

The area of a rectangle is l*w. The perimeter of a rectangle is 2(l+w) or just adding up all 4 sides. Now, all you need to do is math.

A= 3.3 * (20/3) = 22\\P = 2 (3.3 + (20/3)) = 19.93

If your teacher has rounding rules, please follow it.
