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.
Area of a rectangle: a = l * w
The formula for perimeter of a rectangle is: P=2L+2W where L is the length and W is the width of the rectangle.
Area of rectangle is l x b. Where l is length and b is breath of the rectangle.

it is the formula for both a rectangle and a square. remember a square is a rectangle, but a rectangle is not a square (what i mean is a square has to have all 90 degree angles and four sides that are all the same length a rectangle doesn't have all the same lengths. but a rectangle is a shape with all 90 degree angles, and a square fits that discription)
The area formula for the parallelogram is related to the area formula for a rectangle because you can make the parallelogram into a rectangle to find the area.
The formula is for a square and rectangle is A=bh or A=lw
The formula for the area of a rectangle is length x breadth. In order to prove this works, work out an area of a rectangle using that formula.
The formula for finding the perimiter of a rectangle is add up all of its sides
the formula for a rectangle is L x W where L is length and W is width.
If the base is a rectangle, use the formula for the area of a rectangle.
In the formula for the rectangle, put the width equal to the length.
Area of a rectangle: a = l * w
Formula = length times width
A = lw Area of a rectangle = length times width
A rectangle has no volume, it is a 2 dimensional object.
The formula for the center of gravity of a rectangle is: X = (W/2) and Y = (H/2), where X is the distance from the side of the rectangle to the center and Y is the distance from the top of the rectangle to the center, W is the width of the rectangle, and H is the height of the rectangle.
