What is the perimeter in feet?
What is the perimeter, in feet, of the rectangle? Explanation: Divide the area of the rectangle by the width in order to find the length of 14 feet. The perimeter is the sum of the side lengths, which in this case is 14 feet + 4 feet +14 feet + 4 feet, or 36 feet.
What is the length of a rectangle with a perimeter of 72?
Therefore, the length of the rectangle is 25 inches.
What is the area of the rectangular space?
The area A of a rectangle is given by the formula, A=lw , where l is the length and w is the width. Given that, the area is 500 square feet and the width is 20 feet.
What is the length and width of a rectangle with a perimeter of 72?
Since the width of the rectangle (x) is 11 inches, the corresponding length would be 2x + 3 = 2(11) + 3 = 25. Therefore, the length of the rectangle is 25 inches.
