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.
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?
SA = BA + ph SA = BA + LA because LA = ph (perimeter x height)
Oh, what a happy little question! Let's think about shapes that could have a perimeter of 15 and an area of 16. One shape that comes to mind is a rectangle with dimensions 4 by 4. Another possibility is a square with sides of length 4. These shapes show us that there can be different ways to create beautiful combinations of perimeter and area.
Area : 44cm² Perimeter : 30cm
Its perimeter is the sum of its 4 sides Its area is 0.5 times the product of its diagonals
There are different types of geometry formulas such as polygon properties, area formulas, volume formulas, surface area formulas, circle formulas, and perimeter formulas.
You study all the formulas of volume, area, perimeter, and surface area of each shape
They both depend on circumference not perimeter.
perimeter and area. then again i am only in fourth grade gt class

For the perimeter of a polygon you add the sides to find the total distance around the shape. For area, you multiply using the various formulas for different polygons.
Perimeter is the distance around the figure. Add all sides. Area depends on the figure. Triangle --- 1/2 bh Rectangle --- lw. Others --- divide into triangles and find the area of each triangle then add all together.
The shape that has an area of 12 and a perimeter of 16 is a rectangle. To find the dimensions of the rectangle, you can set up equations using the formulas for area and perimeter. Let the length of the rectangle be L and the width be W. The equations would be: 2L + 2W = 16 (perimeter) and LW = 12 (area). Solving these equations simultaneously will give you the dimensions of the rectangle.
It is area, not perimeter!
SA = BA + ph SA = BA + LA because LA = ph (perimeter x height)
