Area of rectangle: 2 times 12 = 24 square feet
To find the area of a rectangle, multiply the length and width. 12ft * 7ft = 84 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
2(21+12) = 66 feet
A 14ft x 12ft room has 168 sq ft of area, provided the room is a rectangle or a rhomboid.
No, a rectangle measuring 26' x 28' has 29% more area than a rectangle measuring 47' x 12'.
Assuming it is a rectangle, it is 156 feet2.
Oh, dude, the perimeter of a rectangle is just adding up all the sides, so for a 12ft by 8ft rectangle, you just do 12 + 12 + 8 + 8, which equals 40 feet. It's like measuring the sides of a fence but with math instead of a tape measure.
