it was Archimedes
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.
Although some have said Archimedes, my opinion is that the formulas for area and perimeter of a rectangle were well known before his time (300BC). The Babylonians in 1500BC knew how to create Pythagorean triples, so I wouldn't be surprised if they knew this. Archimedes did discover more difficult formulas, such as perimeter and area of a circle, and volume of a sphere and a cone.
Stands for perimeter.

Any 5 sided polygon is a pentagon. There is no formula for it. We have formulas for area and perimeter. Perhaps that is what you are asking?

The answer will depend on what the formula is for: the perimeter or area of the segment.
You get the largest area with a circle. Divide the perimeter by (2 x pi), then calculate the area with the formula pi x radius2.You get the largest area with a circle.

There can be no such formula in general. A formula will exist if the area is a regular polygon (or a circle).

The formula for the area of a square is: s * s where s = length of a side The formula for the perimeter of a square is: 4 * s where s = length of a side
The formula for measuring the area of a square is s2, where s is the length of one of the sides. The perimeter would be 4s.
perimeter is different from area because example is in rectangle from formula until you get the answer you can easily see the difference
