the formula for the area of a trapezoid is a=1/2h(b1+b2). which equations area of a trapezoid is a=1/2h(b1+b2). which equations are equivalent to the formula? h=2a/b1+b2, B1=2a/h-b2, b2=2a/b1-h, b2=2a/h-b1, or b1-2a/b2-h?

Answer 1

well, you can start by noting that
a = 1/2 h (b1+b2)
is the same as
hb1 + hb2 = 2a

Now solve for b1 or b2 and see which formula you want.

Answer 2

what’s the answer ?

Answer 3

The answer is b1=2A/h-b2;b1=6 meters

Answer 4

Answer is simple. Imagine x/5+2 if you wanted to put the 2 in the fraction, you would put it in the numerator and multiply "2" by the value in the denominator. So you would get (x+2(5))/5 --> x+10/5
Same logic applies here. Take b(2) in the equation "b1 = 2A/h-b2" and then put it in the numerator and multiply by the denominator which is 2A-b2*h/h which is the final answer 😌👍
