Very easy. Just multiply the two dimensions: 40' x 30' = 1,200 square feet.
40 square feet are 3.716122 square meters.
30 x 40 = 1200 square feet.
multiply 30 by 40 30X40 = 1,200 square feet == ==
40 x 14 = 560 square feet
30 × 40 = 1200 square feet
30 X 40 + 1200 sq/ft
To convert feet to square meters, you would first need to convert the dimensions to square feet. In this case, 5 feet by 8 feet is 40 square feet. To convert square feet to square meters, you would then multiply by a conversion factor of 0.0929. Thus, 40 square feet is approximately 3.72 square meters.
To find the square footage of a rectangle, you multiply the length by the width. In this case, 30 feet multiplied by 40 feet equals 1200 square feet. Therefore, there are 1200 square feet in a 30'x40' area.
The area of 30 feet times 40 feet are 1200 square feet. But, when a house is advertised as containing 'xx square feet of living area', that can include second and third floors or a finished basement or attic, so a 30 X 40 house could be a 6000 square foot home.
30" x 40" is 8.33 square feet.
To calculate the area of a 12x30 room in square yards, first find the area in square feet by multiplying the dimensions: 12 feet × 30 feet = 360 square feet. Since there are 9 square feet in a square yard, divide 360 by 9 to convert to square yards: 360 ÷ 9 = 40 square yards. Therefore, a 12x30 room has an area of 40 square yards.
40 inches times 9 inches are 360 square inches. 360 square inches are 2.5 square feet.
