I still need help on Area and perimeter, for exams. We started Algebra and it's a piece of LI:D Guyz those tips are not helping.

The perimeter is simply the length of the sides added together.
That is easy for polygons for circles and curved shapes you will have to wait until you get to spherical trigonometry.

For area
For regular 4 sided polygons the area is the height multiplied by the height. For triangles it is the 1/2 the altitude times the base and for Circles it is pi times R squared.

For irregular shapes you have to break the shape down into regular shapes figure each one separately and add them together.
 
See I get confused with big words in the text book. And the way it's cut up etc.
 
can you scan question\s from your book & i'll try to solve it
when u see solved question u will understand better >>my math teacher was saying it.
 
Ahh I don't have a question I'm trying to learn before my exams :uuh:

Therein lies the difficulty. You first need to find what type of questions the exam will be testing for and then give an example of ones you don't understand. If you have no trouble understanding your current math book and lessons. You will have no trouble with the exam. If you are having trouble with your current book, give an example of the questions you have problems with.
 
No currently we are at Algebra which is pretty neutral for me.

Have you reached the level where you are name the various types of equations?

I ask that to get some idea as to what type questions will be on your exam.
 
Bro woodrow I don't think we are. An example would be -2t+34=54-6t.
Sister I don't mind , I'm in grade 8.
 
Been years but let me see if I can get this right. I don't think it matters how you start it off you will still get the same answer

-2t+34=54-6t
(I added 6t to both sides which cancels out -6t)

-2+6t+34=54
(-2 + 6t = 4t)

4t+34=54
(I subtracted 34 from both sides to cancel out +34)

4t=20
(I divide 4 into 20 to leave 't' by itself)

t=5?

Adding 6t to both sides I get
6t-2t+34=54-6t+6t
reducing to
4t+34=54
reducing to
4t=20
reducing to
t=5
 
Guyz I don't need help on that. I'm just showing which kind of algebra we are doing.

lol i remember that part of math clearly, what do you need help with then? finals are suppose to be coming up for the first term right? my sister has them in one or two weeks i think
 
Same:uuh: At January 26.:uuh: my first exams. I need help on area and perimeter, also I can do a bit with geometry too.
 
^ Abd I haven't started to study for even one subject :uuh:. Should I start?:uuh:
 
ofcourse, time can be your best friend and your worst enemy, don't think that just cuz u have a lot of time you should put off studying, i'd say get done with studying first then do what ever else u want to

perimeter: add together all the sides

area:

triangle: 1/2bh, mutiply the base and the hight then multiply that by 1/2

Square: LxL multiply the two sides

The area of a parallelogram is b × h

the area of the trapezoid is
1/2 × h × (a + b) .

The area of a circle is Pi × r2 or Pi × r × r, where r is the length of its radius. Pi is a number that is approximately 3.14159.

i won't blame you if you hate finding the area of a circle lol i use to hate it too :-[

this site it really good http://www.mathleague.com/help/geometry/area.htm just open your mind and you'll see the facts going right in :p

all the best in your tests inshallah :)
 
Ugh I'll just check the website out. Jazakallah and hope your sister does well as me.
