area - width = length
Eight feet by eight feet (8' X 8') is a square area. The answer is 64 square feet.But eight times eight feet is 64 (linear) feet, because 8x8=64.
sqrt(8) = sqrt(4) * sqrt(2) = 2 * sqrt(2) = 2 * 1,4142 2,8284(..) To calculate the square root of 2 I needed a calculator. This number is irrational (you can prove that) which means there is no repeating part in the decimals of the square root of 2, and not in the square root of 8 either.
8 feet square is the same as 8 square feet. NOT!8 foot square is 8' x 8' or 64 square feet.
The floor and ceiling are each 72 square feet.In order to calculate the walls, we'd also need to know the height of the room.
There is no "8 square root" of something. You can calculate the square root, or the 8th. root, of something.
To calculate a two-dimentional square or rectangle area: length x width 8 x 8 = 64 square feet
To calculate the square footage, multiply the length by the breadth. So, 10 feet x 8 feet = 80 square feet
multiply the length (in feet) by the width (in feet). For example, if the room is 8 ft by 8 ft, then the room has 16 square feet.
area - width = length
To calculate the area of a rectangle or square, multiply side x side. So to get the square feet in a banner 5 ft by 8 ft, you would multiply 5 x 8, which is 40 square feet.
21 X 12 = yy X 8 = your answer.You do the math.
48 square feet. To calculate square feet simply multiply length by width - the result is the area in square feet.
Eight feet by eight feet (8' X 8') is a square area. The answer is 64 square feet.But eight times eight feet is 64 (linear) feet, because 8x8=64.

A square metre is measuring the area of something. Here, we calculate the area of a rectangle simply by multiplying the length by the width. So the area of this rectangle is:12 * 8 = 96 square metres. You can think of it as 12 * 8 = 96 and a metre * a metre equals a square metre!
80 square feet. To calculate square feet simply multiply length by width - the result is the area in square feet.
