Can you calculate perimeter from area?
Can you calculate perimeter from area?
It’s not possible to determine the perimeter of a rectangle given only the area. The area of a rectangle depends on two unknowns, the length and the width, so you must be given at least one side of the rectangle along with the area to determine the other side and, thus, the perimeter. Let’s look at a sample problem.
What is the formula of area and perimeter of a square?
Perimeter, Area, and Volume
| Table 2. Area Formulas | ||
|---|---|---|
| Shape | Formula | Variables |
| Square | A=s2 | s is the length of the side of the square. |
| Rectangle | A=LW | L and W are the lengths of the rectangle’s sides (length and width). |
| Triangle | A=12bh | b and h are the base and height |
How do you calculate the perimeter of a square?
The perimeter of a square is the distance around the outside of the square. A square has four sides of equal length. The formula for finding the perimeter of a square is 4*(Length of a Side). I the case of a square, all four sides are the same length, so the perimeter is four times the length of a side. Or as a formula: Perimeter = 4S.
How do you find out the perimeter?
The perimeter is the length of the outline of a shape. To find the perimeter of a rectangle or square you have to add the lengths of all the four sides. x is in this case the length of the rectangle while y is the width of the rectangle. The perimeter, P, is: P=x+x+y+y.
What is the formula for perimeter of a square?
Since all sides of a square are equal, we only need one side to find its perimeter. The perimeter of the given square is: a + a + a + a = 4 a units. Hence, the formula of the perimeter of a square = 4 × (length of any one side).
How do you find the perimeter of a figure?
The perimeter is the sum of all sides of a figure to get one length. So, to find the perimeter, the formula is base + height + base + height.
