1. On the aerial photo shown below, a grid has been scribed every 0.25 inch on the photo. If the
photo scale is 1" = 100 feet, what is the approximate area of the field outlined? 570 sq.ft. 1,
500 sq. feet 14, 400 sq.feet 57,000 sq. feet 144,000 sq.feet A benchmark is: A relatively
permanent point that has a known (previously established) or assumed elevation A relatively
permanent point of known horizontal position A temporary point of initially unknown elevation
A relatively permanent point of initially unknown horizontal position Any convenient point on
the ground used to transfer elevation from one point to another
Solution
11. h) 14,400 sqft.
It has min of 19 grid which is approximately fully shaded. 1 grid correspond to 625 sqft hence 19
grid is min 11,875 sqft. Therefore closest option is h.
12. Answer is option (k).
