How to solve shaded regions on a trapezoid is simple.
First find the area of the whole trapezoid, or W but it already gives us that as 21.66 in squared.
Next, find the area of the non shaded region, or NS.
3.8*4.6=17.48 in
Lastly, subtract the NS from the W.
21.66 -17.48 =
NS= 17.48 in squared.
W= 21.66 in squared.
S= 4.18 in squared.
The answer is B- 4.18 in Squared
1,190 cubic units I hope I helped you and plz mark brainliest
Ok....so look at the attached picture
First terms answer is=39x+39
Second term answer is=90x+15
