## b.l.m 3 years ago Look at the formula for the area of a triangle. A = 1 --- 2 bh Which is a solution for h?

1. b.l.m

a= 1/2bh

2. vf321

If you want to get h all by itself, you need to make everything that is multiplied with it 1. For instance, if I want to solve for x: $z=3x$Multiply both sides by 1/3$(1/3)z=(1/3)3x$$z/3=1x$$\frac{z}{3}=x$

3. b.l.m

okay can you show me the steps to solvin mine

4. vf321

Well I'm not going to do it for you but if you compare to mine, what will make a 1/2 become a 1?

5. b.l.m

ooh um subtract? i suck at math excuse me if i wrong

6. vf321

No. What multiplied with 1/2 makes 1?

7. b.l.m

idk x*(1/2)=1

8. vf321

Ugh. no the answer was 2. 2(1/2) = 1. So in the triangle equation multiply by 2 on both sides.

9. b.l.m

oh

10. vf321

Well, do it and show me what you get. multiply by 2 on both sides of A = 1/2 b h

11. b.l.m

multiply by 2 with 1/2?

12. vf321

No. multiply by 2 on both sides of the equation.

13. b.l.m

whats the equation

14. vf321

A = bh/2

15. b.l.m

2b * 2h?

16. vf321

Oh my god dude. Sorry, this is to tough to handle. I'll just give it to you, since arithmetic is too hard. $A = bh/2$Multiply both sides by 2. $2A=bh2/2$Multiply both sides by 1/b $2A/b = bh/b$ $2A/b = h$
