How do you solve this for h?
A=1/2(b1 plus b2)?
This is for a trapezoid, so fine the top length and the bottom length for (b1plus b2) then divide in half for the Area or A
you forgot the h in the original equation, should have been
A = (1/2)(b1 + b2)(h)
then
2A = h(b1+b2)
h = 2A/(b1 + b2)
To solve for "h" in the equation A = 1/2(b1 + b2), we can follow these steps:
Step 1: Start with the given equation A = 1/2(b1 + b2).
Step 2: Multiply both sides of the equation by 2 to eliminate the fraction: 2A = b1 + b2.
Step 3: Subtract b2 from both sides to isolate b1: 2A - b2 = b1.
Step 4: Rearrange the equation to have "h" on one side: b1 = 2A - b2.
Therefore, the equation to solve for "h" is h = 2A - b2.
