25. Find the area of the trapezoid. Leave your answer in simplest radical form. The figure is not drawn to scale.

n200080 [17]

Answer:

Option D. $44\ cm^{2}$

Step-by-step explanation:

we know that

The area of a trapezoid is equal to

$A=\frac{1}{2}[b1+b2]h$

we have

$b1=8\ cm$

$b2=(4+8+2)=14\ cm$

$h=4\ cm$

substitute the values

$A=\frac{1}{2}[8+14](4)=44\ cm^{2}$

If a circle is equal to 365°, take 365° and multiply is by each percentage:
Potatoes - 365° x .088 = 32.12 = 32°
Green Beans - 365 x .119 = 43.435 = 43°
Corn - 365 x .151 = 55.115 = 55°
Carrots - 365 x .108 = 39.42 = 39°
Broccoli - 365 x .197 = 71.905 = 72°
