The height of trapezoid is 18 yards
<em><u>Solution:</u></em>
Given that, trapezoid has an area of 342 square yards
The length of one base is 17 yards, and the length of the other base is 21 yards
To find: height of trapezoid
<em><u>The area of trapezoid is given by formula:</u></em>
![area = \frac{a+b}{2} \times h](https://tex.z-dn.net/?f=area%20%3D%20%5Cfrac%7Ba%2Bb%7D%7B2%7D%20%5Ctimes%20h)
Where "h" is the height
"a" and "b" are the length of base
Here given that,
area = 342 square yards
a = 17 yards
b = 21 yards
h = ?
<em><u>Substituting the values we get</u></em>,
![342 = \frac{17+21}{2} \times h\\\\342 \times 2 = 38 \times h\\\\ 684 = 38h\\\\h = \frac{684}{38}\\\\h = 18](https://tex.z-dn.net/?f=342%20%3D%20%5Cfrac%7B17%2B21%7D%7B2%7D%20%5Ctimes%20h%5C%5C%5C%5C342%20%5Ctimes%202%20%3D%2038%20%5Ctimes%20h%5C%5C%5C%5C%20684%20%3D%2038h%5C%5C%5C%5Ch%20%3D%20%5Cfrac%7B684%7D%7B38%7D%5C%5C%5C%5Ch%20%3D%2018)
Thus height of trapezoid is 18 yards
