Form 3 case study questions

In the form 3 case study 2 there are 2 questions I am struggling with.
Q1 is giving lineal dimensions in acreage. “If the site is 8 acres by 6 acres, what is the maximum volume of earth that the architect can displace?” how can a site be 6 acres long x 8 acres wide?

Q5 states that the correct answer is to replace the bridge, where was it posed that the bridge warrants repair or replacement?

@coachchrishopstock can you please see if you can assist @jplecha in the explanations for these case study questions?
