6 feet
All you need to do is multiply the length by the width, and it doesn't matter in what order you do it. 20ft X30ft= 600 square feet.
To get the answer multiply length and width. The answer will come out to be 1,152 square feet.
120 square feet. To calculate square feet simply multiply length by width - the result is the area in square feet.
assuming that you've measured the room in feet, then square area=Width x Length... so 12ft x 20ft = 240ft2
You don't measure the length and width in square feet. Square feet is an area. You measure the length and width in feet, then multiply them to get the area in square feet.
If the perimeter is 84 feet and the length is twice the width, then the length will be 28 feet and the width will be 14 feet.
Area = Length * Width So Length = Area / Width Length = 132/1q = 132/q feet
1,000,000 cubic feet
To find the area of a rectangle, you multiply the length by the width. In this case, 15 feet x 20 feet equals 300 square feet. This is because you are essentially calculating the area of a rectangle with a length of 15 feet and a width of 20 feet, which gives you the total square footage within that shape.
area = length x width width = area/length 16/8 = 2 feet
Length in feet x width in feet = square feet.
