Hey guys, so I'm having some trouble, not sure if back of the book is wrong or if I'm doing it wrong, probably me though lol.

Alright so I have this graph,

It's asking me to find displacement at 10.0s.

So I know that displacement = area of a velocity- time graph,

therefore at first I assumed it was a trapezoid but that didn't make sense so I used area formulas separately and am getting,

1/2bh+bh+1/2bh

Using this formula I get 39 m/s

1/2(5)(6)+(3)(6)+1/2(2)(6)

^{2}East but in the back it shows as 36 m/s^{2}East.1/2(5)(6)+(3)(6)+1/2(2)(6)
