Answer:

12 meter is the answer......

Answer 2

From 0s to 2s, the displacement traveled by the object during this time interval is given by the area of the triangle made by the graph with the x axis.

Here the displacement is  $\mathrm{\dfrac{1}{2}\times6\times2=6\ m.}$

From 2s to 4s, the displacement traveled by the object during this time interval is given by the area of the rectangle under the x axis.

Here the displacement is  $\mathrm{(4-2)3=2\times 3=6\ m.}$  Even the area is under the graph, we've to take the area as positive. The breadth of the rectangle should be taken as 3 instead of -3.

From 4s to 8s, the displacement traveled by the object during this time interval is given by the area of the rectangle above the x axis.

Here the displacement is  $\mathrm{(8-4)3=4\times3=12\ m.}$

Hence total displacement is  $\mathrm{6\ m+6\ m+12\ m\ =}\ \mathbf{24\ m}.$
