The train would have traveled 40 degrees around the track.
You have to separate the rectangle and the triangle, then find the area of each and add them up.
area of the triangle,
(12×5)÷2=60÷2=30m squared.
area of the rectangle,
12×2=24m squared.
now add them up,
30+24=54m squared.
answer=54m squared
hope this helps......
So we need to first do $75 + $35 = $110 then take $110 * "10% which is 0.1" 'so $110 *0.1 = $11 so $11 is the tax
so now again add $75 + $35 = $110 take $110 + $11 = $121
$121 is her final total
