Can you calculate area from perimeter?
What is its area? Divide the perimeter by 4: that gives you the length of one side. Then square that length: that gives you the area.
What is the formula of area if perimeter is given?
The perimeter P of a rectangle is given by the formula, P=2l+2w , where l is the length and w is the width of the rectangle. The area A of a rectangle is given by the formula, A=lw , where l is the length and w is the width.
What is the formula for area?
Given a rectangle with length l and width w, the formula for the area is: A = lw (rectangle). That is, the area of the rectangle is the length multiplied by the width. As a special case, as l = w in the case of a square, the area of a square with side length s is given by the formula: A = s2 (square).
What is area divided by perimeter?
The area of a shape is the amount of two-dimensional space that it covers. The ratio of the perimeter to the area of a shape is simply the perimeter divided by the area.
What is perimeter and area?
Area refers to the space occupied by a shape or an object or a surface. Perimeter refers to the measure of the length of the outline or boundary of a shape, an object or a surface. Area is measured in square units. For example, if the dimensions are in inches, then the area is expressed as square inches.
How do you find the perimeter and area of a rectangle?
Perimeter of a Rectangle
- Remember the formula for perimeter and area of a rectangle. The area of a rectangle is a = length * width, while the perimeter is p = (2 * length) + (2 * width)
- Substitute the known values into the area formula. 36 = 4 * w.
- Substitute values for length and width into the perimeter formula.
Is dimension and perimeter the same?
A dimension is one of the measurable characteristics that determine the shape of the figure. It might be the length of one of the sides of a polygon (a figure with straight sides) or the radius of a circle. Perimeter is a measure of the distance along the outside edge of the figure.
What is perimeter and area examples?
For example, to fence the garden in your house, the length required of the material for fencing is the perimeter of the garden. If it’s a square garden with each side as a cm then the perimeter would be 4a cm. The area is the space contained in the shape or the given figure.
