Formula of a rectangle?

There is no formula for a rectangle. There are formula for calculating its area, perimeter or length of diagonals from its sides, or it is possible to calculate the length of one pair of sides given the other sides and the area or perimeter, or the two lots of sides given area and perimeter and so on.


How do you calculate the length and breadth of a rectangle given the area and the perimeter?

Perimeter = (2 lengths) + (2 widths)1/2 of the perimeter = (length) + (width)Area = (length) x (width)So if you're given the area and the perimeter:-- Look for factor-pairs that multiply to give the area.-- The right pair of factors is the pair that add to give 1/2 of the perimeter.Example:Area = 24Perimeter = 22Factor pairs that make 24:1 x 242 x 123 x 84 x 6Which pair is it ?Perimeter = 221/2 the perimeter = 11.Look at the sums:1 + 24 = 252 + 12 = 143 + 8 = 11


How are factors related to area?

Some people relate factor pairs to the sides of a rectangle. Length times width equals area; factor times factor equals product.


How do you use the dimensions of a rectangle to find factor pairs?

I think you are thinking of using the rectangles like you use Punnet squares. One side is multiplied times the other side and the product is put in the inside squares. This is handy when trying to factor expressions that are polynomials.


What is the perimeter of a rectangle that has an area of 432 feet?

Ah, what a lovely question! To find the perimeter of a rectangle, we need to know both the length and width. Since the area is 432 square feet, we can find the dimensions by factoring 432 into pairs of numbers until we find a pair that could be the length and width of the rectangle. Once we have the dimensions, we can simply add up all the sides to find the perimeter.


A rectangle has a perimeter of 28 inches The length of one pair of sides is 8 inches per side What is the length of each of the other sides?

A rectangle has a perimeter of 28 inches. The length of one pair of sides is 8 inches per side. What is the length of each of the other sides? Six in.


How do you write a program to find the area and perimeter of a rectangle?

CLS PRINT "PROGRAM: Calculate both perimeter/area of rectangle" PRINT INPUT " Length"; length INPUT "Breadth"; breadth PRINT PRINT "Perimeter: "; 2 * (length + breadth) PRINT " Area: "; length * breadth END


How do you find the length and width of a rectangle if you only know the perimeter the perimeter is 26?

Its impossible to isolate both the length and width, but you can figure out the sum of one pair of length and width, which is 13.


What is the relationship between the rectangles for number and factors of the number?

One rectangle for each factor pair.


How many rectangles can the factor pairs of 84 make and how would you draw them?

One rectangle per factor pair, six total.

How do you find rectangles using the prime numbers?

Prime numbers have one factor pair, hence one rectangle.
