Answer:
[tex]{A = \frac{b_1+b_2}{2}h}[/tex]
Step-by-step explanation:
"half the sum of its 2 bases (b1 and b2)"...
the sum of the bases would be getting divided by two ---> [tex]\frac{b_1+b_2}{2}[/tex]
"times height"
the quotient would be multiplied by the given height ---> * h
Putting it all together, we would get:
[tex]\frac{b_1+b_2}{2}*h\text{ or } \frac{b_1+b_2}{2}h[/tex]
The second version is generally preferred.
[tex]\boxed{A = \frac{b_1+b_2}{2}h}[/tex]
Hope this helps.
