It is a hypercube in 4-dimensional space with an area of 3200 quartic feet.
It is: 40*80 = 3200 square feet
The area is 80 square feet.
40*40 = 1600 square feet
1 acre = 43560 square feet⇒ 80 acres = 80 x 43560 square feet= 3484800 square feet
100' x 100' if it's perfectly square. 125 feet by 80 feet will also give 10,000 square feet, as will 250 feet by 40 feet.
It is: 40*80 = 3200 square feet
= 40 x 80 = 3200 sq feet
22.2 square feet.
3,200 square feet. To calculate square feet simply multiply length by width - the result is the area in square feet.
Multiply 8 X 5 = 40 80 X 50 = 4,000 Sq Ft Multiply 80 and 50 to get 4000 square feet
6.3245553 To get square feet, multiply base times the height (or the two sides). So, assuming the dimensions you offered are in feet, 10' X 4' = 40 square feet.
80*80 = 6400 square feet
Square feet is length times width. If something is 160 square feet, it could be 2 x 80, 4 x 40, etc.
The area is 80 square feet.
40 ft × 80 ft = 3200 sq ft
40*40 = 1600 square feet
80 square feet is 7.43224 square meters.
