What is the formula of area and perimeter of rectangle?

What is the formula of area and perimeter of rectangle?

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 perimeter in math formula?

PERIMETER FORMULAS

PERIMETER FORMULAS
Rectangle The perimeter of a rectangle = 2 ×(p + q) p,q = length of adjacent sides
Triangle The perimeter of a triangle = a + b + c a, b, c = lengths of sides
Quadrilateral The perimeter of a quadrilateral = a + b + c + d a, b, c, d = lengths of sides

What is the formula of a perimeter?

Perimeter, Area, and Volume

Table 1 . Perimeter Formulas
Shape Formula Variables
Square P=4s s is the length of the side of the square.
Rectangle P=2L+2W L and W are the lengths of the rectangle’s sides (length and width).
Triangle a+b+c a,b , and c are the side lengths.

How do you calculate area of perimeter?

To calculate the perimeter, you use addition; to calculate the area, you use multiplication. Determine the perimeter of a triangle or rectangle by knowing the length of all of the sides of the figure and then adding these numbers together. The perimeter is the sum of all sides of a figure to get one length.

What is the equation for finding the perimeter?

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. If the base is 10 inches and the height is 5 inches, you would have: Perimeter: 10 + 5 + 10 + 5 = 30 inches. Determine the area of a rectangle by using multiplication.

How to find perimeter using area?

The relationship between area and perimeter of a square is that perimeter is 4 4 times the square root of the area.

  • To get the perimeter from the area for a square,multiply the square root of the area times 4 4.
  • Perimeter is always measured in linear units,which is derived from the area’s square units.
  • How to get perimeter from area?

    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)

  • Substitute the known values into the area formula. 36 = 4*w.
  • Substitute values for length and width into the perimeter formula.
