It is: 20 times 20 = 400 square feet
Do you mean a real square with the side length of 20 feet? Then 20 feet times 20 feet is 400 square feet.
20 feet times 40 feet = 800 square feet
If the numbers are in feet then 86 times 20 = 1720 square feet
The area of 12 foot times 20 foot are 240 square feet.
If the given dimensions are in feet then 20 times 24 = 480 square feet
If the given dimensions are in feet then 24 times 20 = 480 square feet
Length times width will give you area. So this comes out to 400 square feet.
There are: 20 feet times 30 feet = 600 square feet
There are: 20 times 9 = 180 square feet
There are: 20 times 9 = 180 square feet
Multiply 12 by 20 so 240 square feet. Length times width.
