## Sheradon.burkett 2 years ago Please help! last question and I'm done! The lengths of the bases of an isosceles trapezoid are shown below.(picture attached) If the perimeter of this trapezoid is 32 units, what is its area? F. 44 square units G. 110 square units H. 88 square units J. 55 square units

Okay, what is the length of the two remaining sides?

they aren't given....

4. whpalmer4

Well, not explicitly. What is the formula for the perimeter?

5. timo86m

perimeter = all the sides the 2 sides are the same p=14+8+2x

I think the answer is 44?

7. timo86m

legs are 5

Can you figure out the height of the trapezoid?

10. whpalmer4

"44?" isn't an answer choice. When we're done, you'll definitely know what the answer is.

11. him1618

the height is 4? ... and yes, 44 is an answer choice.

13. whpalmer4

44 is an answer choice. "44?" is not.

14. him1618

extremely smart

15. whpalmer4

There's a difference between taking a stab at an answer, and understanding what you've done so that you know what the answer is.

16. whpalmer4

You can know that you've got it right.

17. whpalmer4

My old math teacher would always say "is that an answer, or a prayer?" :-)

18. whpalmer4

How did you find the height?

i think it's 4...

20. timo86m

use pythogorean theorem

21. whpalmer4

I know the height is 4, and the area is 44. I want to make sure that you can look at a problem like this and find the answer and be confident that you've done it right. That's a good outcome, right?

22. timo86m

and it is 4
