When looking for a picture frame in size 20 by 30 you will find many of them are made form a material called M,D,F this can be found in many shapes and sizes.
20x30= 600
600=20 * 30
20x30
A 20x30 frame can be purchased from places such as: amazon, ebay, argos and also specialist framing shops. They come in many different colours depending on what is needed.

There are: 20 feet times 30 feet = 600 square feet
The answer will depend on what units the floor is measured in: 20x30 square inches? sq feet? sq metres? Since you have not bothered to provide that information, I cannot provide a sensible answer. Furthermore, there are various sizes for sheets of plywood as well.
600 square feet (20x30=600)
I think that 23x38=874 because you can split it up like this:(20x30)+(3x8)+(3x30)+(8x20)=874.
around 300 from a good buyer
Square is simply multiplying the length times the width. An example: A room is 20 feet long and 30 feet wide. Multiply 20x30=600 square feet.
