Velocity-Time Graph

Using this graph, how far does the runner travel in 16 s?
(Vs = 12 m/s)

I tried doing area under the curve and it produced 174 m but I ended up getting it wrong.
Did I do something wrong? Is there another way to approach this problem?

With no V axis values it's hard to tell.

Oh I see Vs is evenly spaced. Each unit is 3.

That means that each unit block on the graph is 2 x 3 = 6 m

And there are 1x4/2 + 4x4 + 1x2/2 + 2x1 + 2x2 = 25 blocks times 6 m per block is 150 m
