Multiply the numbers together: 1800 sq ft
160 ft. squared
To find the square footage of a space that is 40 feet by 40 feet, you multiply the length by the width. So, 40 feet × 40 feet equals 1,600 square feet. Therefore, the square footage of a 40 x 40 area is 1,600 square feet.
40 square feet. Just multiply length by width - the answer is the square footage.
2,400 square feet. Just multiply length by width - the answer is the square footage.
800 square feet. Just multiply length by width - the answer is the square footage.
There is not enough information to answe. If approximately square it could be about 40 x 50, but a circular room of about 30 feet in diameter would have the same square footage.
It is: 40*80 = 3200 square feet
The square footage of a rectangle is calculated by multiplying its length by its width. For a space that is 10 feet wide and 40 feet long, you would multiply 10 by 40, resulting in a total square footage of 400 square feet.
Add the length of each wall to get the total perimeter of the room. In this case 10+10+10+10=40. Then multiply the40 by the height of the room. In this case 8. The answer 40*8=320 is the square feet of the walls in the room.
Simply put multiply 15 by 40 to get the square footage. This would be 600 square feet.
To find the total square footage of a room, you multiply the length by the width. In this case, a 35 x 40 room would have an area of 1,400 square feet. This calculation is derived from the formula for the area of a rectangle, which is length x width.
