you don't. that's like asking how many dollars are in 10 feet. the units "linear feet" and "square feet" represent two totally different types of quantities. if you have a rectangle made up of 216 linear feet, the area (in square feet) could be practically anything. If the sides are 50 and 58, the perimeter is 216 linear feet and the area is 2,900 square feet. But if the sides are 10 and 98 feet, the perimeter is still 216 linear feet, while the area is now 980 square feet.
Area is length x width. 12 x 18 = 216, so the shop has 216 square feet
The square root of 216 is ~14.7
72
You would find the area by multiplying the width by the length, so the area would be 216 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.
Feet and linear feet are the same measurement. Therefore, 216 feet is equal to 216 linear feet.
There are 24 square yards in 216 square feet. To convert square feet to square yards, divide the total square feet by 9 (since 1 square yard is equal to 9 square feet).
216 square feet
216 square inches is 1.5 square feet.
18 feet x 12 feet = 216 square feet 216 square feet = 20.0670566 square metres
216 square feet.
216 square feet (12 x 18 = 216)
216 square feet. Length x width = square feet.
144 square inches = 1 square footArea = (216-in x 14-in) = 3,024 square inches = 21 square feet
With great difficulty (that is it is impossible) without further information:216 square feet represent an area; it has twodimensions (like a width and a depth)linear feet (or just feet) represent a length; it has one dimension (and is used to measure things like width and depth).To reduce an area by one dimension so that it becomes a length requires dividing by a length.So without knowing the shape of the area and what length of the area you want to measure (and possibly some length of the area), conversion is impossible. Indeed, 216 sq feet can be converted into any linear feet you want to! examples:Radius of circle with area 216 sq ftradius = √(216 sq ft ÷ π) ~= 8.29 ftWidth of rectangle with area 216 sq ft and length 36 ftwidth = 216 sq ft ÷ 36 ft = 6 ftCircumference of circle with area 216 sq ftcircumference = √(4 x 216 sq ft x π) ~= 52.10 ftLength of perimeter of square with area 216 sq ftperimeter = 4 x √(216 sq ft) ~= 58.79 ftBase of triangle with area 216 sq ft and height 12 ftbase = 2 x 216 sq ft ÷ 12 ft = 36 ft
