to find the perimeter you must add all sides.

and to find area you have to multiply lenght and width

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)

the perimeter is how long the surrounding of the shape is for example if a side of a square is 1 and there are 4 sides the perimeter would be 4 4x1=4 the area is how much space a shape takes up so if the sides of a square are 2 the area would be 4squared 2x2=4 formulas for a square A=BxH P=length of sides added up

Area : 44cm² Perimeter : 30cm

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.

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.

SA = BA + ph SA = BA + LA because LA = ph (perimeter x height)

It is area, not perimeter!

Perimeter = 4*Side so that Side = Perimeter/4 Area of a rhombus = Side * Altitude so Altitude = Area/Side = Area/(Perimeter/4) = 4*Area/Perimeter
