Does anyone know how to answer this question I'm having a lot of trouble with it?
Helen [10]

Answer:

h = \frac{2A}{(b+c)}

Step-by-step explanation:

Formula for the area of a trapezoid is,

Area (A) = \frac{1}{2}(b+c)h

Here b and c are the bases and 'h' is the height of the trapezoid.

2A = 2[\frac{1}{2}(b+c)h]

2A = (b + c)h

\frac{2A}{(b+c)}=h

Therefore, formula for the height of the trapezoid will be,

h = \frac{2A}{(b+c)}
