20 feet x 10 feet = 200 square feet
300 square feet. To calculate square feet simply multiply length by width - the result is the area in square feet.
Area of rectangle = 38ft x 20ft = 760ft2 1sq yd = 1yd x 1yd = 3ft x 3ft = 9ft2 760ft2 / 9 ~= 84.4 sq yds.
Exactly 20 feet.
20 ft x 20 ft = 400 square ft
20ft² = 1.858m²
20 feet x 10 feet = 200 square feet
There are: 20 times 9 = 180 square feet
20ft x 28ft = 560ft2
Multiply together 25 ft X 20 ft = 500 sq.ft.
30ft*20ft = 600 sq ft
There are: 20 times 9 = 180 square feet
You can't have cubic feet in an area. Area is for two dimentions and volume is for 3 dimentions.20ft by 20ft is 400ft2
20ft * 15ft = 300 square feet.
Multiply the two dimensions to get the area. The calculation will give you 400 square feet.
There are 609.6 centimeters in 20 feet. 20 feet x 30.48 centimeters/1 foot = 609.6 centimeters 1 foot = 30.48 centimeters
420 square feet. (21 x 20 = 420)
