Suppose sqrt(A) = B ie the square with sides B has an area of A and its perimeter is 4*B.
Now consider a rectangle with sides C and D whose area is A.
So C*D = A = B*B so that D = B*B/C
Perimeter of the rectangle = 2*(C+D) = 2*C + 2*D = 2*C +2*B*B/C
Now consider (C-B)2 which, because it is a square, is always >= 0
ie C*C + B*B - 2*B*C >= 0
ie C*C + B*B >= 2*B*C
Multiply both sides by 2/C (which is >0 so the inequality remains the same)
2*C + 2*B*B/C >= 4*B
But, as shown above, the left hand side is perimeter of the rectangle, while the right hand side is the perimeter of the square.

What is the relationship among these shapes triangle squares rectangles parallelograms quadrilaterals pentagon hexagon and octagon?
Oh, dude, those shapes are like a big happy family tree! So, like, a square and a rectangle are both quadrilaterals, while a triangle is its own cool shape. Parallelograms are like the chill cousins of rectangles, and pentagons, hexagons, and octagons are just showing off with their extra sides. It's all just shapes, man.

When are perimeter used?
Perimeter is used in several real world situations.For example, if your living room is thirteen feet long and twenty feet wide, you know you can't get a rug whose sides are bigger than 13x20.Another common example is fencing. When you are putting up a fence you don't really care about the area. You are looking for how much fencing you will need, which means you need to know how big the perimeter of the land is.In math, perimeter is used in geometry and trigonometry (among other places), and is sometimes used to help student's practice their algebra skills is middle schools.
How do i convert square meter into length and width?
A square meter is a unit of area. Suppose we only consider quadrilaterals of a given area, say 16 square meters. This is the area of the following rectangles (among others): 1 by 16 meters, 2 by 8, 4 by 4 (a square), 8 by 2, and 16 by 1. So to convert an area in square meters into a length and width pair, choose an edge length, and divide the area by that length to get the other edge length. Another example: Suppose we have a rectangle whose area is 20 square meters. Take one edge to be 5 meters, so you get 20/5 = 4 meters as its other edge.
What relations among the sides and angles of rectangles are also true of parallelograms?
Opposite sides are parallel and opposite angles are equal
When you want to carpet the entire floor is that perimeter or area?
That is the area. The perimeter is the measure around something, and it is relevant, among other things, to know how much fencing you need for a lot.
If you have 100 feet of chicken fencing for the chicken pen to hold the most chickens inside what shape should you make the pen square circular or they both provide the same area?
You should make the pen circular. A circular pen maximizes the area enclosed by the fencing for a given perimeter length, allowing you to fit more chickens inside. This is because a circle has the largest area for a given perimeter among all shapes.
