Perimeter is the distance AROUND any particular object where area is the amount of space inside the object (2dimentional).
Let's say you have a yard 10 feet long, by 11 feet wide.
The perimeter is the distance AROUND your yard or 10+10+11+11 = 42ft
The AREA is the amount of space inside or L*W or 10*11 = 110ft^2
Suppose I change the dimensions of the yard without changing its perimeter (42 ft) and see what happens to the area. Suppose the length and width are 20ft and 1 ft respectively. The perimeter is still 20+1+20+1=42. The area however is 20X1 =20 ft2 Now if we take the yard to be a square one of 10.5 ft side then the perimeter still remains 42 ft. but the area becomes 110.25 ft2. Now suppose I assume that the perimeter of a circle is 42 ft. What will the area of such a circle be? Now we know that the circumference of a circle is 2x3.14(pi)Xr = 42 ft. Therefore r = 6.687 ft. r2= 44.715 ft2 therefore area of the circle is 4xpixr2= 561.63 ft 2. Thus we can deduce that given a known perimeter a circular shape has or occupies the largest area. What happens if the shape is irregular? Say a irregular polygon? Would my deduction that the cicrular shape has the largest area remain valid?

It doesn't. But you can calculate the ratio (relationship) between any two measurements you can make on the table. Such measurements might be (among others): * Its length * Its width * Its diagonal * Its area * Its height * Its perimeter
Well, honey, first you need to know the shape you're dealing with to calculate the perimeter. Once you've got that number, you can't just wave a magic wand and turn it into square meters. Perimeter is measured in linear units, while square meters measure area, so you'll need more information to make that conversion.
perimeter is all the sides added, area is the base times the height, and volume is on a prism u multiply the three different measurements
pi is the ratio of the perimeter of a circle to its diameter. The Greek letter, pi, is the first letter of the word perimetros (Greek for perimeter).
