The formula you need is:
area = length x width
Replace the numbers you know; solve for the number you don't know.
12 x 10 = 120 square feet
A(rect) = w * l = 12ft*10ft = 120ft2Length * width = area10 * 12 = 120
12 ft * 18 ft = 20.07 metres, approx.
96 square feet. Multiply length by width - the result is the area in square feet.
two sides 12 ft and two sides 10 ft is 120 sq ft (12*10)
Length is 12ft, width is 4 ft. 2 x (length + width) = perimeter = 32 ft ⇒ length = 16ft - width [1] length x width = area = 48 sq ft Using [1] above: ⇒ (16ft - width) x width = 48 sq ft multiplying out and rearranging: ⇒ width2 - 16 x width + 48 = 0 factorizing: ⇒ (width - 4)x(width - 12) = 0 Thus width = 4 or 12, so using [1] above: ⇒ width = 4ft, length = 16 - 4 = 12ft or width = 12ft, length = 16 - 12 = 4ft Convention is that the length is larger than the width, thus rectangle is 12ft long by 4 ft wide.
56-ft
Area=length x width, A=lxw=10ft x 12ft=120ft2
2*(length + width) = 54 feet.
To find the area of a rectangle, multiply length x width: 12 x 10 = 120 sq ft
12 x 10 = 120 square feet
A(rect) = w * l = 12ft*10ft = 120ft2Length * width = area10 * 12 = 120
12 ft * 18 ft = 20.07 metres, approx.
For area measurements, you multiply the length by the width. Here the calculation gives you an answer of 2,400 square feet.
Multiply width by length to get the area. The answer would be 360 square feet or 40 square yards.
This cylinder will require 1.4 cubic yards of concrete (this assumes a length of 12' and a width of 2').
96 square feet. Multiply length by width - the result is the area in square feet.
