The answer will depend on the units for 80 and 120 - inches, feet, miles, metres etc - which you have chosen not to disclose. It is therefore impossible to give a sensible answer.
80 m2 equates to about 861.11 square feet.
80 feet x 8 feet = 640 square feet.
1600 square feet 20 x 80 = 1600
There are 80*80 = 6400 sq feet.
6400 square feet
80 ft x 120 ft = 9600 ft2 of concrete
To calculate the area of a rectangle, you multiply the length by the width. In this case, the length is 120 feet and the width is 80 feet. So, the area would be 120 feet x 80 feet = 9600 square feet.
86,400 Sq. Ft.
80*80 = 6400 square feet
It is: 120+80+120+80 = 400 feet
80 acres = 3,484,800 square feet
44.4 square feet.
80 m2 equates to about 861.11 square feet.
80 feet x 8 feet = 640 square feet.
32 feet times 80 feet = 2,880 square feet
One acre has 43,560 square feet. Divide the number of square feet, 9,600 by that and you get the number of acres. This gives you an answer of .220 acres.
80' x 120' = 9,600 square feet = 1,066-2/3 square yards = 0.2204 acre (rounded)
