Answer: 91
Step-by-step explanation:
the equation to find the area of a trapezoid is as follows:
A = (a+b)/2h
So A = 6+20 which is 26
then you divide 26 by two which gives you 13, then multiply by 7
Small sample, because there needs to be more that just three people to determine if the study is true.

4 x 5 houses in 3 x 5 days
20 hosues in 15 days
