ok so this polygon is an irregular polygon there is no equation to find it

Other answers:

so first you need to cut the polygon into pieces that can be calculated
Suggestion: find the biggest one, then subtract the irrelevant parts.

@MLG360GABEN What is the formula to find area of a rectangular?
and what formula to find triangles?
umm A=bh/2 ?
to find area of a square also. You need them all to solve this problem. Please, state them out
@MLG360GABEN what is the formula for a square?
A= a divided by 2 ?
no the area of a square is A=bh b=base h=height; sound familiar?
kind of
im confused
yes, now look at the pic i drawn above, there is a triangle towards the top left......right?
yes
would that be 40?
no can you write the formula for the triangle and try again?
A= bh x 2
@MLG360GABEN you just stated the formula above...... A=(bh)/2
so 72?
what does the slash mean?
divide
ohh
18?
or 36?
here'\[A= \frac{ (20\times20) }{ 2 }\]s the formula:
give me a hint
well, 20x20 is 400
is it lower or higher than a 100
because i got 200
well you are correct
so its 200?!
YEAAAAA
thank YOU for all your time im sorry if I was frustrating
no problem
thanks bye :)
now you need to find the area of the rectangel to the right
ok
so you remember the formula?
A=bh
so its A=6x36 right?
can you find the area?
i'll try
its just multiplying :)
so its just 216
great!
is that all did i do it
now you need to subtract the smaller triangle from 216
210
you still need the formula for triangle! A=(bh)/2
A=(6x6) / 2
228?
no the area of the triangle is 18
yes i got that
now subtract 216-18
198
198
now add that to the area to the big triangle to the left
200+198=???
398
goood job!! thats your final answer
yay!!
:)
so how should I explain this in my essay?
hmmm everything we have talked about before, how you split up the polygon into pieces and found the areas. then you added them together and got the final answer. and dont forget to mention the formulas
ok thanks :)
bye
good luck :)
