Area of rectangle: 2 times 12 = 24 square feet
12 * 9 = 108 square feet = 12 square yards
12 x 10 = 120 square feet
To find the area of your rectangle, multiply 16ft by 12ft. This gives you 192. So your answer would be 192 square feet.
56-ft
To find the area of a rectangle, multiply length x width: 12 x 10 = 120 sq ft
A 14ft x 12ft room has 168 sq ft of area, provided the room is a rectangle or a rhomboid.
2(21+12) = 66 feet
No, a rectangle measuring 26' x 28' has 29% more area than a rectangle measuring 47' x 12'.
The area of a 12-ft by 8-ft rectangle, expressed in metric units, is 8.919 square meters. (rounded)
Let x be the width of the rectangle. The length will therefore be x + 10 and the volume will be x(x + 10) = x2 + 10x The questuion gives the numeric value for the area as 264, so x2 + 10x = 264 => x2 + 10x - 264 = 0 => (x + 22)(x - 12) = 0 => x = -22 or x = 12. Since only a positive number can be used as a real length, the width of the rectangle is 12ft and the length is 12 + 10 = 22ft. So the dimensions of the rectangle are 22ft x 12ft.
Area=length x width, A=lxw=10ft x 12ft=120ft2
