A triangle has a base of 10 centimeters and a height of 7 centimeters. Which is the total area of the triangle?

Question

terenzreignz · Answer

Area of a triangle is half the product of its base and height.

anonymous · Answer

Thank you

anonymous · Answer

Is it the same for parrallelograms?

terenzreignz · Answer

No... if you have a base and height for a parallelogram, the area is just their product... 
base x height

As opposed to a triangle, whose areas is
$\Large \frac12$  x base x height

anonymous · Answer

Okay so I use base x height for the parallelogram?

terenzreignz · Answer

Yup. :)

anonymous · Answer

Okay thank you :)

anonymous · Answer

can you help me with one more please

terenzreignz · Answer

Hit me.

anonymous · Answer

The dimensions shown are an approximation. Using these dimensions, which is the approximate area of ABC?

anonymous · Answer

What do I do for this problem?

terenzreignz · Answer

You have a base, and you have a height, so just use the formula for the area of a triangle :)

anonymous · Answer

And thats it?!

terenzreignz · Answer

That's it...

anonymous · Answer

I feel dumb now.. but thank you hahha

terenzreignz · Answer

But something is amiss...

terenzreignz · Answer

I need professional opinion on this... @amistre64 impossible triangle?? http://assets.openstudy.com/updates/attachments/51924e7de4b0d270317e4723-amber1214-1368543261483-pi.gif

anonymous · Answer

Im alwasy stuck on this problem can you help again please?

terenzreignz · Answer

What's the question?

anonymous · Answer

I need the area for the problem

terenzreignz · Answer

You have two triangles... basically, get both of their areas and add them up...

anonymous · Answer

You are so much simpler then the teacher I have at school.. thanks so much!

amistre64 · Answer

9-9-9 is possible,  but that 8 in the middle, is representative of sqrt(3), with 4.5 being representative of 1

4.5^2 + 3 =abt 81 by chance?

amistre64 · Answer

thats didnt write up like i wanted lol

amistre64 · Answer

8^2 + 4.5^2 about 9^2?

terenzreignz · Answer

I guess... or 4.5 times the square root of 3 is about 8... Sorry, @amistre64 , I got a little obsessive compulsive with that one :D

terenzreignz · Answer

Oh, wait, it says the dimensions were an approximation...
my bad, sorry for the bother :)

amistre64 · Answer

its close enough for the square block into the round hole iq test :)
