Diagonal = 18*sqrt(2) = 18*1.414214 = 25.45584 feet
To calculate the area in square feet, you first need to convert the dimensions to feet. Since 1 foot is equal to 12 inches, 18 inches is equal to 1.5 feet. Therefore, 18 inches by 18 inches equals 1.5 feet by 1.5 feet, which is 2.25 square feet.
The formula for finding the area of a rectangle is width multiplied by length. In this case, 12 feet by 18 feet is equal to 216 square feet.
Area is length x width. 12 x 18 = 216, so the shop has 216 square feet
18 and two thirds square yards
The answer is 270 square feet.
216 square feet (12 x 18 = 216)
288 square feet.
A circle with a diameter of 18 feet has an area of 254.5 square feet.
A 6 foot by 3 foot area would be 18 square feet.
