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.

## What is area formula?

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 lens formula?

Lens equation or lens formula is an equation that relates the focal length, image distance, and object distance for a spherical mirror. It is given as, Lens Formula – 1/u + 1/v = 1/f. where.

## Is circumference a straight line?

Circumference: The circumference of a circle is the distance around it. Diameter: Any straight line that passes through the centre of the circle to two points on the perimeter. Radius: Any straight line that originates at the centre of a circle and ends at the perimeter.

## How do you figure out a diameter?

If you are given the area of a circle, the diameter is equal to the square root of four times the area divided by pi (diameter = √ (4 x area) / pi).

## How do u find the diameter of a line?

Divide the circumference by pi, approximately 3.14, to calculate the diameter of the circle. For example, if the circumference equals 56.52 inches, divide 56.52 by 3.14 to get a diameter of 18 inches. Multiply the radius by 2 to find the diameter.
