Do you know the formula for the area of a trapezoid?

3. chancemorris123

no clue

4. chancemorris123

so what you think it is i have the screen shot

5. Mertsj
6. Mertsj

Plug the given information into that formula and solve for h.

7. chancemorris123

but there is no h

8. Mertsj

That's what you have to find.

9. chancemorris123

so how cna i do btime btime h

10. Mertsj

You are given the area and both bases. Find h

11. Study_together

The formula for the height of a trapezoid is $2\frac{ A }{ a+b }$ A=area a=base b= 2nd base So the height is 4.0 cm

12. chancemorris123

oh ok but one thing where you get the 2 from?

13. Study_together

I'm sorry it should be H=height

14. chancemorris123

ok thank you

15. Study_together

Can I get a medal?

16. chancemorris123
