Hi. I got the following question:
A perimeter is set up around a crime scene that spans 3 city blocks in each direction. Each city block is 20 yards wide. What is the total area covered by the perimeter?
To solve this, I calculate the area of one block as 20*20 = 400 yards. Then I took 3 city blocks west, 3 east, 3 north, and 3 south. So 3*4=12.
To get the total area, I have 400*12 = 4800 yards. But this is wrong. What am I doing wrong here?
Thanks!
