Unit 8 - Checkpoint Score: 88/100 12/13 answered Question 13 Progress saved Done 0/8 pts 3 98 Details Joe-Bob's neighbor Daisy-Bo is leaving town for two months and asks Joe-Bob to keep an eye on her house. Never one to miss an opportunity to make money from his couch, Joe-Bob decides that her lawn is the perfect location for a temporary car parking lot for paying customers. The lawn is a four-sided polygon with sequential side lengths of $a = 17.5$, $b = 20.7$, $c = 22.5$, and $d = 25$ (all measured in yards). The angle between the two shortest sides is $\theta = 116^\circ$. Joe-Bob never applied himself in math class, so it is up to you, dear student, to determine the area of the lawn to be converted into a parking lot, rounded to the nearest square yard. Area = $yd^2$
