You said that <u> A = 1/2 b h</u>
Multiply each side by 2 : 2A = b h
Divide each side by 'h' : <em>2A/h = b</em>
U set up an equation: 80 x 8/5
Then u can cross multiply bc 5 goes into 80
It goes into 80 exactly 16 times
So new equation: 16 x 8
Multiply that out and u get 128
4.5 + 4 + 5.25 = 13.75 miles in total (13 and 3/4)
