18 x 7 = 126 square feet
18 and two thirds square yards
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.
sqrt(324) = ±1818the square root is 18
Area is length x width. 12 x 18 = 216, so the shop has 216 square feet
The diagonal of an 18 inch square is about 25.46 inches. (18 times the square root of 2).
18 ft Diagonal of a square is the square root of 2, times the side.
It's the square root of the sum 18 feet squared plus 18 feet squared. 18 feet squared is 324 square feet. 2 x 324 square feet = 648 square feet. The square root of 648 square feet is about 25.46 feet.
Ah, the diagonal of a square is a special thing indeed. If you have a square that's 18 units on each side, you can use a little math magic to find its diagonal. By using the Pythagorean theorem, you'll see that the diagonal of this square would be 18 times the square root of 2. Just remember, there's always a way to find beauty and harmony in even the most geometric of shapes.
A = 18 square units.
Use Pythagoras' therom: 32+32 = 18 The square root of 18 is 4.242640687 units which is the length of the diagonal.
Side = diagonal/1.5Side = 12Perimeter = 12 * 4Perimeter = 48
A square whose diagonal is the diameter of the circle. So, if it is a circle with diameter 18 units then the diagonal of the square is 18 units and so its side is 9*sqrt(2) = 12.7 units.
a square foot is simply a square that is 1 foot by 1 foot if the area you need to measure is 3 feet by 6 feet you have 18 square feet (3 x 6 = 18) if the area is 10 feet by 10 feet you have 100 square feet (10 x 10 = 100) hope this helps!
Suppose the side of the square is s, then length of diagonal = s*sqrt(2) s*sqrt(2) = 18 so s = 18/sqrt(2) = 12.7 units.
The perimeter = 12 feetthen the square diagonal = 12/4 = 3 feet The diagonal2 = 3x3 + 3x3= 18 feetThe diagonal = square root of 18 = 3x 21/2 feet = 3 x 1.4142 = 4.2426 feet
216 square feet (12 x 18 = 216)
