Answer 3

billbell can you help

Answer 4

Can you tell me the formula for the area of a triangle?

Answer 5

a=1/2BH

Answer 6

Good. In this question what equation would represent the relationship between the base, B, and the height, H?

Answer 7

multiplication?

Answer 8

What does it tell you about the two in the question, in words?

Answer 9

ohh the height is twice the base

Answer 10

How can you write that as an equation?

Answer 11

2b

Answer 12

=?

Answer 13

What is 2B equal to (from the question)?

Answer 14

2b=81*1/2b

Answer 15

No. What the question says is simple. 2B = H. The height is twice the base. (Try not to think so hard!)

Answer 16

Take the facts one at a time.

Answer 17

You're ok with that?

Answer 18

ohh thanks

Answer 19

We now know H = 2B and we also know that A=81. We had A = BH / 2.

Therefore we can write 81 = B(2B) / 2 or B^2 = 81

Therefore B=9 and we're finished.
