Lol
This shape has turn to work and pass.
No attempt?

femi4:
4 and 3

Area: 1/2*4*3 = 6

Correct

Should I bring solution?

Anyone?

i can see new people commenting on this, u are welcome

correct

anyone? or should i drop workings

i know u guys can do it but u are just making little mistakes

MacMath:
Simple as ABC, the answer is 12

Try again sir

MacMath:
where is the"semicircle" ?

Two quadrant of same radius make a semicircle.
Did you get?

Martinez39:
Haba, this is simple. The area of the yellow whatever is 9 unit².

Try again sir

You are asked to find how many cakes are in the middle

Martinez39:
Haba, this is simple. The area of the yellow whatever is 9 unit².

Lol, you did not get the unknown sir
Read the question again

Find the unknown ?

Anyone?

Darivie04:
Out of all the basic mathematics subjects Geometry/Shapes is probably my weakest but your problems are always fun to try.

Thank you sir,
I will keep them coming

Someone sent this to me two days ago.

If you have any idea to solve this drop it

If you know you can solve it

Darivie04:
@ifada123 maybe you can start posting proof based geometry questions.

Geometry Right?
I have them too, is like you are very good at it,
I will post one today.

It is unfortunate that no female can answer this,
FG maybe correct, "most of them are not doing well in maths"

Martinez39:
|PO| = |OQ| = a
|PO|² + |OQ|² = |PQ|² , let |PQ| = y
2a² = y², therefore a = y/√2
The distance d from O to the midpoint of |PQ| is
d = a Cos (π/4) = y/2
The distance s from O to the midpoint of |NM| is
s = y/2 + y = 3y/2

Length of chord |NM| is
|NM| = 2 √(R² - s²) , R = √10
y = 2√(10 - 9y²/4)
y² = 4(10 - 9y²/4) = 40 - 9y²
10y² = 40
Therefore y² = 4 units²

Good one
You can also use cosune rule,

Martinez39:
Sorry, I made a mistake. I erroneously squared my answer.

X = 4 units².

Show workings so that people will learn from you sir

Martinez39:

X = 4 units².

Very correct
Show them workings

Martinez39:


X = 16 units².

@ifada123, I will use this month and next to learn basic geometry. I must conquer all your shapes.

Not correct try again
The area of the full quadrant is
1/4 x22/7×√10×√10=7.8539cm^2
So that square will have lesser area.
Try again sir

Martinez39:


X = 16 units².

@ifada123, I will use this month and next to learn basic geometry. I must conquer all your shapes.

OK sir "every shape must be solved"
That's one of my l anthem

Martinez39:
I surrender. Can't tackle this one.

Try my recent Shape

Martinez39:
I surrender. Can't tackle this one.

I will post solution later Sir

The difficulty level of this is low,
You ladies should not fall our hand

Hmmm no one?

Anyone?

Find the exert area (X) of the square PNMQ.
Let us see the first to get the connection, then we can learn from him/her.
What a man can do woman can do better
Equal rights and equal responsibilities
What ever is your slogan, please solve.
FG is insinuating that most of you can't do this, don't tell me their research is accurate.
Prove them wrong!
"Every shape must be solved"
The men are not left out anyway.

Anyone?

Martinez39:
Wait till evening. I will solve it when it come back home in the afternoon.

OK sir, I will wait.
But I will post the one for today. Let it be two shapes.
