Answer:
c = 11.3 yards
Step-by-step explanation:
The area (A) of a trapezium is calculated as
A = h (a + b)
where h is the perpendicular height and a, b the parallel bases
Here A = 416.955, h = 20.9, a = 28.6 and b = c, thus
× 20.9 × (28.6 + c) = 416.955, that is
10.45(28.6 + c) = 416.955 ( divide both sides by 10.45 )
28.6 + c = 39.9 ( subtract 28.6 from both sides )
c = 11.3 yards

We have 29 people who chose fishing out of 18+29 people who filled out the survey. We don't use 60 because not everyone filled out the survey, and we're only focusing on survey participants. The "times 100" at the end will move the decimal point 2 spots to the right, and convert it to percent form.
For example, if you had 2 people who liked fishing out of 8 total then 2/8 = 0.25 = 25% of the people like fishing.
For this case we are asked the following question:
