Answer 1

First do you know the equation to find the area of a trapezoid?

Answer 2

You there?

Answer 3

Here I'll just get you started.

The equation is \[A = \frac{ a+b }{ 2 }h\]

Answer 4

To find h (or height), rearrange the equation to isolate h.

Answer 5

soory i am back

Answer 6

You're fine.
Do you have it from here or would you like me to help you further?

Answer 7

yes please

Answer 8

Do you know how to rearrange equations?

Answer 9

no

Answer 10

Okay so like I said earlier we need to get h by itself in the equation:
\[A = \frac{ a+b }{ 2 }h\]
First we should multiply both sides by 2 which will give us.
\[2(A)=(a+b)h\]
Next, divide both sides by (a+b) to get
\[\frac{ 2(A) }{ a+b }=h\]
Make sense or do you have any questions?

Answer 11

is a\[2\left( a \right)\] 216

Answer 15

thx your a MLG gamer lol

Answer 16

wait whats a+b

Answer 17

Haha no, my gaming is pure hobby.
But a=the top base of the trapezoid (or in this case 8)
and b=the bottom base of the trapezoid (or in this case 10)

Answer 18

Look on the picture you posted, and you'll see what I'm talking about.
