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
Answer: The charge was right.
Step-by-step explanation:
If he charged $18 per hour, it means he charged $18 for 60 minutes. He worked for 2 hours 15 minutes which is (60 ×2) + 15 = 135 minutes. For 135 mins, (135 ×18)÷ 60 = 40.5.
He drove 21 miles to his house and 21 miles back. That is 21×2= 42. And for $0.27 = $11.34.
Adding the costs, 40.5 + 11.34 = $51.84
