## How do u find the mean

How to Find the Mean.

The mean is the average of the numbers.

It is easy to calculate: add up all the numbers, then divide by how many numbers there are.

In other words it is the sum divided by the count..

## What’s the perimeter and area

The perimeter is the sum of all the side lengths of a shape. The area is the amount of two dimensional space a shape occupies. Above is the graph of a square yard.

## How do you describe an area

Area is the term used to define the amount of space taken up by a 2D shape or surface. We measure area in square units : cm² or m². Area is calculated by multiplying the length of a shape by its width.

## What is the formula for area

Perimeter, Area, and VolumeTable 2. Area FormulasShapeFormulaVariablesSquareA=s2s is the length of the side of the square.RectangleA=LWL and W are the lengths of the rectangle’s sides (length and width).TriangleA=12bhb and h are the base and height4 more rows

## How do you find an area example

To find the area of a rectangle, multiply its height by its width. For a square you only need to find the length of one of the sides (as each side is the same length) and then multiply this by itself to find the area. This is the same as saying length2 or length squared.

## What is a perimeter formula

The perimeter is the length of the outline of a shape. To find the perimeter of a rectangle or square you have to add the lengths of all the four sides. x is in this case the length of the rectangle while y is the width of the rectangle. The perimeter, P, is: P=x+x+y+y.

## Why is area and perimeter important

The unit and topics of area and perimeter are important to mathematics because they are the physical aspects of mathematics. They are the foundation for understanding other aspects of geometry such as volume and mathematical theorems that help us understand algebra, trigonometry, and calculus.

## How is area used in everyday life

What real-life situations require us to use area? ▫ Floor covering, like carpets and tiles, require area measurements. Wallpaper and paint also call for area measurements. Fabric used for clothing and other items also demand that length and width be considered.

## Why is area squared

Why is the area of a square a side square? A square is a 2D figure in which all the sides are of equal measure. Since all the sides are equal, the area would be length times width, which is equal to side × side. Hence, the area of a square is side square.

## What is an area in math

In geometry, the area can be defined as the space occupied by a flat shape or the surface of an object. The area of a figure is the number of unit squares that cover the surface of a closed figure.
