The question is: What fractions of the beads are blue or green ?
The answer is: <em>7/12 of the beads</em> are either blue or green.
Applying the equation for the area of the trapezoid, it is found that the height is of 10 cm.
The <em>area of a trapezoid</em> is <u>half the multiplication of the sum of the bases and the height</u>, that is:
![A = \frac{h}{2}(b_1 + b_2)](https://tex.z-dn.net/?f=A%20%3D%20%5Cfrac%7Bh%7D%7B2%7D%28b_1%20%2B%20b_2%29)
For this problem, we have that:
, hence:
![A = \frac{h}{2}(b_1 + b_2)](https://tex.z-dn.net/?f=A%20%3D%20%5Cfrac%7Bh%7D%7B2%7D%28b_1%20%2B%20b_2%29)
![205 = \frac{h}{2}(20 + 21)](https://tex.z-dn.net/?f=205%20%3D%20%5Cfrac%7Bh%7D%7B2%7D%2820%20%2B%2021%29)
![20.5h = 205](https://tex.z-dn.net/?f=20.5h%20%3D%20205)
![h = \frac{205}{20.5}](https://tex.z-dn.net/?f=h%20%3D%20%5Cfrac%7B205%7D%7B20.5%7D)
![h = 10](https://tex.z-dn.net/?f=h%20%3D%2010)
The height is of 10 cm.
