Explanation: The area of the trapezoid can be calculated using the following rule: Area of trapezoid = [tex] \frac{b1 + b2}{2} * h[/tex] where: b1 is the length of the first base b2 is the length of the second base h is the height
Now, in the given we have: b1 = 15.8 yd b2 = 21.8 yd h = 11.7 yd
Substitute with the givens in the above equation to get the area as follows: area = [tex] \frac{15.8 + 21.8}{2} * 11.7 = 219.96 yd^2[/tex]
