There is not enough information given to find and area.

Below are 2 of and infinite number of quadrilaterals that meet this description.

It is visually clear that the one on the right has a bigger area than the one on the left

try dividing

minus 20 from both sides

Anyway, if you are interested enough to respond I will discuss my thoughts with you.

No the asker means a quadrilateral.  (that is what I would call it anyway)  Those are the langth of the sides.

When I was at school, many moons ago, our 'play areas' were bordered by 4 buildings.

These were referred to as quadrangles.  (literally 4 anlges)

Each year of students had a different quadrangle in which we were meant to be.

I put 'play area' in inverted commas becasue we were not allowed to play.

It was an all girls school and we were expected to behave like 'ladies' 

Some of you kids do not know how lucky you are.  LOL

breeding a Ww with a ww you can get     Ww, Ww, ww, ww

Ww will be white and ww will be yellow

so 50% are expected to be yellow.    

Nice work guest, let's see if I get the same answer  

How many positive three-digit integers less than 500 have at least two digits that are the same?

how many have the units and tens digit the same?   10*4 = 40

How many have the units and hudreds the same?     4*10=40

How many have the tens and hudreds the same?     4*10=40

How many have all 3 the same?    4 (must subtract twice becasue it has already been counted 3 times)

so how many have at least 2 the same = 120-8 = 112

I have an answer but I am a little dubious about it.

I have looked back at your history and you have never once interacted with or thanked and answerer. (interaction is more important than thanks)

Some of the answers provided led to discussions between 2 or more answerers.  You never got involved.

You have given an answerer a point only once.

So it apprears that you are not really interested in learning from your answers or leaving any good impression on the other answerers here.

Perhaps you should change your attitude if you want help to continue being given.

I know you have answered a couple of questions for other people and I thank you for that.

Thanks Tiggsy,

That makes sense.
