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>

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>,

Thus height of trapezoid is 18 yards
we know that

Since, we have to find 1 foot^2
so, we will take square both sides



so, we can see that it is not equal to 12 inch^2
that's why

Step-by-step explanation:
All that are true:
sin(C) = square root 3/2
tan(C) = square root 3
sin (B) = 1/2
