Hey there!
It would have been better if you showed the picture with more detail.
But, for anyone else look at this, you need to understand that each grid line equal's 10 feet. I don't know if you can see, but it say's it clear in the top of the page.
So, I believe that we need to find to distance of [tex]AH \ and \ DE[/tex].
So, we should count each grid . . . . . .
14 x 10 = 140 feet.
Hope this helps
