**Area & Perimeter**

Equation

L × W = A

Problem

l= 7

w=2

A=?

**What is Area**

Definition: In mathematics the area of a plane figure refers to the number of square units the figure covers. The area is the inside shape or space measured in square units. In rectangles and in squares, a simple calculation of length times width will give the number of square units. The square units could be inches, centimeters, yards etc. or whatever the requested unit of measure asks for. There are many formulas used to determine the area of many common shapes or polygons.

ANSWER

A= 14

L= length

W= width

Questions?

The way you solve this is you plug in what your given into the equation

then you solve the equation

Relationship with carpentry

2L+2W=P

add length to the width

Plug in all the things your given

L=5

W=2

P=?

P=14

Problem

Both Area and Perimeter have a massive impact on many of the things that you do for example:

Examples of relationship of area

When a person is painting a wall.

In this situation the person would have to calculate the amount of materials that you need.

Relationship between perimeter and carpentry

How much wall does the paint for each bucket cover?

how much wall can each person cover every hour?

Both of these will tell how much man hours you will need to pay for and how many buckets do you need ?

Area of a triangle

L X W =A

(B x H)/2 = A

B= Base

H= Height

Find The Area of a square

Problem 2

Find the area of the triangle

B=5

H=6

A=?

Steps

First you have to plug in all of the things that you are given

Then you solve

A=15

Answer

Don't forget to divide by 2

When you make a form you need to know how long, tall, and wide you want the object to be. So that the form is do correctly. Therefor you will need to know how to use perimeter.

Both Area and Perimeter share the same numbers,but other than that they share no Relationship.

This is only correct when you are working with an objects that is like a square.

This dose not apply when using triangle shaped shapes.
