Question

If the Original height, h, of a triangle is doubled, and the original of base, b, is tripled, which expression would represent the area of the resulting triangle?
a, ½‎bh
b, 3bh
c, 6bh
d, 12bh

Answer 1

3bh it'll be b

Answer 2

Thank you

Answer 3

you're not allowed to say answers

Answer 4

And on top of that, his answer is wrong.

@Martha.Ln do you know the formula to find the area of a triangle?

Answer 5

Not exactly

Answer 6

Okay...this gets sticky...but I'm gonna go there anyway.

The formula is 1/2*B*H

That formula holds true regardless of how you twist or rearrange a triangle's measurements.

In this case, your question asked "which expression would represent the area" of a triangle.

So which of your answers "represents the area" of a triangle?

Answer 7

So, it's ½‎bh, a ?

Answer 8

Correct!!

Answer 9

^^ Thanks alot!

Answer 10

No problem! Glad I could help! :-)

BTW, just to illustrate your problem further,
Suppose you had a triangle with a height of 2 and a base of 2
Its area would be 1/2*B*H = 1/2*2*2 = 2
Now double its height and triple its base, and you have a triangle with a height of 4 and a base of 6
The area of this one is STILL 1/2*B*H = 1/2*6*4 = 12

Taadaaa!! :-)

I'll go away now... :-)
