solve for h

The formula for finding the area of a trapezoid is
A = 1/2 (b1 + b 2)h where A represents the area
of the trapezoid, b1 and b2 are bases, and h represents the height. Solve the formula for h.

I know the answer is
h =

2A/b1 + b2

but I don't understand why...can you explain step by step

I tried dividing b1 + b2 from both sides..i just don't know..please and thank you

Okay here's our equation:

A=1/2h(b1+b2)
First, we need to get rid of the fraction, so we need to multiply both sides of the equal sign by 2 (the denominator)
Multiplying the denominator by the denominator will cancel 2 out which will leave us with 1, & anything times 1 is itself so we remove 1 too.

Now we have 2A=h(b1+b2)
Since we're trying to solve for h, we need to get rid of b1+b2. H is being multiplied by b1+b2 & division is the opposite of multiplication so we'll divide H by b1+b2. To keep the equation equal we need to divide both sides.

Diving h(b1+b2) by (b1+b2) will leave us with only h. We can't get an answer from 2A/b1+b2 since there are no like terms, so that'll be our final answer.

h= 2A/b1+b2

The b1+b2 quantity is just a number, like any other. You can divide by it, just like you divide by the 1/2...

1/2 (b1 + b 2)h = A
(b1+b2)h = 2A
h = 2A/(b1+b2)

hold on gimmie ur snap u seem funny ngl

does anyone got this in units?

my test as them in

20 units²

22 units²

24 units²

28 units²

To solve for h in the formula A = 1/2 (b1 + b2)h, we need to isolate h on one side of the equation.

Step 1: Start by multiplying both sides of the equation by 2 to eliminate the 1/2 coefficient:

2A = (b1 + b2)h

Step 2: Divide both sides of the equation by (b1 + b2) to isolate h:

h = 2A / (b1 + b2)

By performing these steps, we successfully solved the formula for h.

2a/b=h
