## Reaper534 2 years ago The height of a trapezoid is 13 inches, one of the bases measures 22 inches. If the area of the trapezoid is 318.5 square inches, find the length of the other base.

44*13?

5. Callisto

Let x be another base area = (x + 22) x height /2 You have area and height. Can you plug in the numbers there and solve for x?

6. Reaper534

area=318.5 318.5=(x+22)x heoght 2 do i go from there?

7. Reaper534

ahhh i can awnser its to hard >.<

8. Callisto

What is the height?

9. Reaper534

13inc

10. Callisto

So, you get 318.5 = (x+22) x13 Do you know how to solve it?

11. Reaper534

yes

12. Reaper534

32.5

13. Reaper534

thx a lot

14. Reaper534

wait dont i do (13x+286)

15. Callisto

318.5 = (x+22) x13 You can first divide both sides by 13, then subtract 22 from both sides.

16. Reaper534

ohh ok

17. Reaper534

2.5

18. Reaper534

mind helping with 2 more?

Quadrilateral MATH is a square. If MA = 2x – 5 and AT = x + 10, find the perimeter of the square
